High-performance direct borohydride-hydrogen peroxide fuel cell using Ni foam-supported Ni-Co nanoparticles as a noble-metal free anode electrocatalyst

The Ni-Co nanoparticles with various Ni/Co ratios are immobilized on a Ni foam (NF) template, coated with reduced graphene oxides (rGO), and used as a novel noble-metal-free anode electrocatalyst for enhanced performance direct borohydride fuel cells. The electrochemical active surface area (EASA) of Ni50Co50 /rGO/NF (1515 cm2) catalyst is 45.5 times larger than NF (33.3 cm2). A comprehensive study of direct borohydride-hydrogen peroxide fuel cell (DBHPFC) by Pt/C (0.5 mg cm−2) as a cathode and Ni50-Co50/rGO/NF as an anode is accomplished, so an open-circuit potential (OCP) of 1.90 V and the maximum power density of 309 mW cm−2 is obtained at 60 ◦C. These results show that electrocatalyst Ni50Co50/rGO/NF is a suitable candidate for use as an electrocatalyst in DBHPFC due to its low cost, ease of synthesis, excellent structural stability, and high catalytic performance.

Synergistic enhancement of oxygen vacancy enrichment and morphology regulation in CeO2-NiCo2O4 heterostructure catalysts for high-performance cathodes in direct borohydride-hydrogen peroxide fuel cells

Hydrogen peroxide (H2O2) emerges as a viable oxidant for fuel cells, necessitating the development of an efficient and cost-effective electrocatalyst for the hydrogen peroxide reduction reaction (HPRR). In this study, we synthesized a self-supporting, highly active HPRR electrocatalyst comprising two morphologically distinct components: CeO2-NiCo2O4 nanowires and CeO2-NiCo2O4 metal organic framework derivatives, via a two-step hydrothermal process followed by air calcination. X-ray diffraction and transmission electron microscopy analysis confirmed the presence of CeO2 and NiCo2O4, revealing the amalgamated interface between them. CeO2 exhibits multifunctionality in regulating the surface electronic configuration of NiCo2O4, fostering synergistic connections, and introducing oxygen deficiencies to enhance the catalytic efficacy in HPRR. Electrochemical measurements demonstrate a reduction current density of 789.9 mA·cm−2 at −0.8 V vs. Ag/AgCl. The assembly of direct borohydride-hydrogen peroxide fuel cell (DBHPFC) exhibits a peak power density of 45.2 mW·cm−2, demonstrating durable stability over a continuous operation period of 120 h. This investigation providing evidence that the fabrication of heterostructured catalysts based on CeO2 for HPRR is a viable approach for the development of high-efficiency electrocatalysts in fuel cell technology.

Co‑MOF-Derived Flake-Like Co3O4 Supported Pd Nanoparticles as High-Performance Hydrogen Peroxide Electroreduction Catalysts

Development of highly efficient catalysts for the hydrogen peroxide reduction reaction (HPRR) has been a focus of research for fuel cells using hydrogen peroxide (H2O2) as an alternative cathode oxidant. The carbon-doped flake-like cobalt oxide electrode (Co3O4@C NF) was prepared on nickel foam (NF) by annealing the metal organic framework (MOF). A Co3O4@C/Pd NF (CPNF) electrode was derived from Co3O4@C NF by supporting Pd nanoparticles. Half-cell tests demonstrated that the CPNF electrode exhibited outstanding catalytic performance. The CPNF electrode displayed a high current density of 932 mA cm−2 at −0.8 V (vs Ag/AgCl). This aligns with its low activation energy (7392.8 J mol−1). The electron transfer numbers for the Co3O4@C NF and CPNF electrodes were 2.97 and 3.32, respectively. Incorporating CPNF as the cathode of Direct borohydride-hydrogen peroxide fuel cell (DBHPFC) yielded notable catalytic performance, with a peak power density of 68 mW cm−2. The CPNF electrode exhibited remarkable stability, sustaining continuous current discharge for over 20 h. These electrochemical properties result from the structural characteristics obtained through MOF annealing, which increases the number of exposed active sites and enhances ion transport. Therefore, CPNF stands as a promising cathode catalyst for DBHPFC.

Bipolar Membranes for Direct Borohydride Fuel Cells-A Review.

Direct liquid fuel cells (DLFCs) operate directly on liquid fuel instead of hydrogen, as in proton-exchange membrane fuel cells. DLFCs have the advantages of higher energy densities and fewer issues with the transportation and storage of their fuels compared with compressed hydrogen and are adapted to mobile applications. Among DLFCs, the direct borohydride-hydrogen peroxide fuel cell (DBPFC) is one of the most promising liquid fuel cell technologies. DBPFCs are fed sodium borohydride (NaBH4) as the fuel and hydrogen peroxide (H2O2) as the oxidant. Introducing H2O2 as the oxidant brings further advantages to DBPFC regarding higher theoretical cell voltage (3.01 V) than typical direct borohydride fuel cells operating on oxygen (1.64 V). The present review examines different membrane types for use in borohydride fuel cells, particularly emphasizing the importance of using bipolar membranes (BPMs). The combination of a cation-exchange membrane (CEM) and anion-exchange membrane (AEM) in the structure of BPMs makes them ideal for DBPFCs. BPMs maintain the required pH gradient between the alkaline NaBH4 anolyte and the acidic H2O2 catholyte, efficiently preventing the crossover of the involved species. This review highlights the vast potential application of BPMs and the need for ongoing research and development in DBPFCs. This will allow for fully realizing the significance of BPMs and their potential application, as there is still not enough published research in the field.

Effect of anode conditions on the performance of direct borohydride–hydrogen peroxide fuel cell system

Direct borohydride–hydrogen peroxide fuel cells (DBHPFCs) are attractive power sources for space applications. Although the cathode conditions are known to affect the system performance, the effect of the anode conditions is rarely investigated. Thus, in this study, a DBHPFC system was tested under various anode conditions, such as electrocatalyst, fuel concentration, and stabilizer concentration, to investigate their effects on the system performance. A virtual DBHPFC system was analyzed based on the experimental data obtained from fuel cell tests. The anode electrocatalyst had a considerable effect on the mass and electrochemical reaction rate of the fuel cell system, but had minimal effect on the decomposition reaction rate. The NaBH4 concentration greatly influenced the mass and decomposition reaction rate of the fuel cell system; however, it had minimal impact on the electrochemical reaction rate. The NaOH concentration affected the electrochemical reaction rate, decomposition reaction rate, and mass of the fuel cell system. Therefore, the significant effects of the anode conditions on the electrochemical reaction rate, decomposition reaction rate, and mass of the fuel cell system prompt the need for their careful selection through fuel cell tests and system analysis.

PdCu nanoparticles modified free-standing reduced graphene oxide framework as a highly efficient catalyst for direct borohydride-hydrogen peroxide fuel cell

A novel electrode of PdCu nanoparticles modified free-standing reduced graphene oxide (rGO) framework (PdCu@rGOF) is fabricated via electrodeposition and chemical reduction and employed to the direct sodium borohydride-hydrogen peroxide fuel cell (DBHPFC). The resultant catalyst reveals excellent catalytic performance towards hydrogen peroxide (H2O2) electroreduction reaction (HPRR) and sodium borohydride (NaBH4) electrooxidation reaction (BOR) along with low activation energy (Ea). Numerically, the PdCu@rGOF electrode delivers an HPRR current density of 455.2 mA cm−2 at 0 V (2 mol L−1 H2SO4+1.3 mol L−1 H2O2). Additionally, the current density of BOR reaches up to 1065.3 mA cm−2 at 0 V for 2 mol L−1 NaOH and 0.3 mol L−1 NaBH4. Meanwhile, the mechanism studies show that HPRR and BOR catalyzed by PdCu@rGOF mainly relates 2-electron-transfer process and quasi-8-electron-transfer process, respectively. Subsequently, PdCu@rGOF is assembled into a fuel cell, yielding the optimal power density of 188.9 mW cm−2. The open circuit potential (OCP) of DBHPFC is about 1.70 V at 293.15 K. The superior electrochemical performance of the optimized electrode can be attributed to the distinctive architecture and the strong adsorption and bond-breaking ability of Pd nanoparticles. This work indicates that the as-prepared PdCu@rGOF can be a promising catalyst for DBHPFC.

Ag–Ni nanoparticles supported on multiwalled carbon nanotubes as a cathode electrocatalyst for direct borohydride–hydrogen peroxide fuel cells

In this study, an Ag–Ni electrocatalyst supported on multiwalled carbon nanotubes (MWCNTs) was investigated to develop a new type of cathode electrocatalyst for direct borohydride–hydrogen peroxide fuel cells (DBHPFCs). Monometallic electrocatalysts consisting of Au, Ag, or Ni have previously demonstrated relatively high catalytic activity and selectivity. The characteristics of each catalyst (Au/MWCNTs, Ag/MWCNTs, and Ni/MWCNTs) were determined through various techniques, such as scanning electron microscopy, energy dispersive X-ray spectroscopy, transmission electron microscopy, and X-ray diffraction; additionally, their performance was evaluated using a fuel cell test. Based on the results, Ag and Ni were selected to construct a bimetallic electrocatalyst, owing to their relatively superior catalytic selectivity at high current densities. Ag–Ni/MWCNT catalysts with various atomic percentage ratios were prepared, and their characteristics were investigated. Among the bimetallic electrocatalysts, Ag41Ni59/MWCNTs exhibited the highest maximum power density. Furthermore, Ag41Ni59/MWCNTs exhibited good catalytic selectivity even at high operating temperatures. The prepared Ag–Ni bimetallic electrocatalyst has moderate catalytic activity and selectivity and is more cost effective than Au and Ag catalysts; therefore, it can be used as a new type of cathode electrocatalyst for DBHPFCs.

Effect of cathode conditions on performance of direct borohydride–hydrogen peroxide fuel cell system for space exploration

Fuel cell tests are conducted under various cathode conditions to investigate the effect of cathode conditions on the performance of a direct borohydride–hydrogen peroxide fuel cell (DBHPFC) system. The efficiency and mass of the virtual DBHPFC system are estimated based on experimental data obtained from the fuel cell tests. The type of cathode electrocatalyst considerably affects the performance and mass of the fuel cell system. Ni is the most suitable for the cathode owing to its high fuel utilization efficiency and low cost. The H2O2 concentration has a minimal effect on the performance of the fuel cell system but considerably affects the mass of the fuel cell system. The mass of the fuel cell system negatively correlates with the H2O2 concentration. The H3PO4 concentration and operating temperature have a negligible effect on the performance and mass of the fuel cell system; 5 wt% H3PO4 is sufficient to suppress the decomposition reaction and improve the fuel cell performance. Operation at room temperature is recommended for high fuel utilization efficiency. The decomposition reaction rate affects the efficiency and mass of the DBHPFC system. Consequently, the decomposition and electrochemical reaction rates should be considered when determining suitable cathode conditions for the DBHPFC system.

Carbon nanotube-graphene supported bimetallic electrocatalyst for direct borohydride hydrogen peroxide fuel cells

At present study, carbon nanotube-graphene (CNT-G) supported PtAu, Au and Pt catalysts were prepared by microwave-assisted synthesis method to investigate the direct liquid-fed sodium borohydride/hydrogen peroxide (NaBH4/H2O2) fuel cell performance. Prepared catalysts were characterized by TGA, XRD, TEM, ICP-OES, cyclic voltammetry and rotating disc electrode (RDE) voltammetry. The catalysts were tested in a single NaBH4/H2O2 fuel cell with 25 cm2 active area to evaluate fuel cell performance. The effects of temperature and fuel concentration on fuel cell performance were examined to observed best operating conditions. As a result of direct NaBH4/H2O2 fuel cell experiments, maximum power densities of 139 mW/cm2, 125 mW/cm2 and 113 mW/cm2 were obtained for PtAu/CNT-G, Au/CNT-G and Pt/CNT-G catalysts, respectively. PtAu/CNT-G catalyst showed the enhanced NaBH4/H2O2 fuel cell performance, which was higher than the Pt/CNT-G catalyst and Au/CNT-G catalyst at 50 °C. The enhanced NaBH4/H2O2 performance can be attributed to synergistic effects between Pt and Au particles on CNT-G support providing a better catalyst utilization and interaction. These results suggest that the prepared PtAu/CNT-G catalyst is a promising anode catalyst for NaBH4/H2O2 fuel cell application.

Gold-based bimetallic electrocatalysts supported on multiwalled carbon nanotubes for direct borohydride–hydrogen peroxide fuel cell

Au-based bimetallic electrocatalysts supported on multiwalled carbon nanotubes (MWCNTs) were investigated to improve the selectivity and activity of the catalysts for direct borohydride–hydrogen peroxide fuel cells (DBPFCs). Au–Pd and Au–Ni catalysts were used as the anode and cathode catalysts, respectively. The Au-based bimetallic catalysts with various atomic percentage ratios were investigated using inductively coupled plasma optical emission spectroscopy, transmission electron microscopy, Brunauer–Emmett–Teller analysis, scanning electron microscopy, energy dispersive spectroscopy, X-ray diffraction, and fuel cell tests. Among the Au-based bimetallic catalysts, Au49Pd51/MWCNTs was found to be the most suitable for the anode and Au74Ni26/MWCNTs was the most suitable for the cathode. The effects of the operating temperature and operation time on the catalytic selectivity and activity were also investigated to evaluate the performance of the bimetallic catalysts. It was found that the Au-based bimetallic catalysts had good catalytic selectivity and activity even at an elevated operating temperature and a maximum power density of 279.5 mW/cm2 was obtained at 52.0 ± 2.0 °C when Au49Pd51/MWCNTs (anode) and Au74Ni26/MWCNTs (cathode) were used for the DBPFC electrodes. It was also found that the Au-based bimetallic catalysts showed stable performance for 70 min. Thus, the Au-based bimetallic catalysts can be widely used for DBPFCs.

Reduced graphene oxide foam supported CoNi nanosheets as an efficient anode catalyst for direct borohydride hydrogen peroxide fuel cell

Abstract Catalytic performance and NaBH4 utilization are two crucial concerns in the electrooxidation of NaBH4. To improve the inherent properties of regular performance and low fuel utilization of the transition metal Co and Ni, an efficient anode catalyst of ultra-thin CoNi nanosheets modified novel 3D self-supported reduced graphene oxide foam is prepared in this work. The alkaline condition borohydride oxidation reaction on the prepared catalyst is investigated in a typical three-electrode system. The prepared catalyst shows a high performance due to the large electrochemical active surface area, low activation energy (8.29 kJ·mol−1), and the small electrochemical impedance it embraced. Linear scan voltammetry recorded in a low concentration of NaBH4 suggests that borohydride oxidation is a first-order reaction on the prepared catalyst. Based on the unique structure of the catalyst, which is useful to capture the hydrogen and perform further oxidation of hydrogen, higher utilization of NaBH4 achieved on the catalyst. Besides, the prepared anode catalyst applied to a direct borohydride-hydrogen peroxide fuel cell (DBHPFC). The results of polarization curve and power density curves, as well as stability research, all indicate that the as-prepared catalyst is a highly efficient anode material for application in DBHPFC.

Novel self-supported reduced graphene oxide foam-based CoAu electrode: An original anode catalyst for electrooxidation of borohydride in borohydride fuel cell

An original three-dimensional self-supported reduced graphene oxide (rGO) foam is successfully prepared in this work. This novel support material, modified with Co nanosheets and Au nanoparticles, is employed as a high-performance catalyst for NaBH4 electrooxidation under alkaline condition. The surface chemical component and morphology of the catalyst is characterized by X-ray diffraction pattern, X-ray photoelectron spectroscopy, scanning electron microscope. The synthesized electrode exhibits excellent performance (1.35 A cm−2 at 0 V) towards NaBH4 electrooxidation. The unique structure of rGO foam caused a large electrochemical active surface area (EASA(Au) = 390 m2 g−1), low electrochemical impedance, as well as 55.4% utilization efficiency of NaBH4. Also, catalytic kinetic parameters during the electrooxidation reaction of NaBH4 in a low NaBH4 concentration are investigated. Results indicate that oxidation of BH4− is a first-order reaction, and the exchanged number of electrons obtained at the CoAu/rGO foam electrode is 6.9. Finally, we practically apply it to a direct borohydride-hydrogen peroxide fuel cell (DBHPFC). This work suggests that the prepared rGO foam is an excellent current collector, and CoAu/rGO foam electrode is a promising anode catalyst to apply in DBHPFC.

Nitrogen-Doped Carbon Catalysts Modified with Au-M (M = Co, Ni, Cu) Nanoparticles As the Anode Material for Direct Borohydride-Hydrogen Peroxide Fuel Cells

Direct borohydride-hydrogen peroxide fuel cells (DBHPFCs) have several advantages such as high theoretical cell voltage (2.11-3.02 V), high energy density (12-17 kWh kg-1) and, finally, no CO poisoning during their operation. Therefore, anode material is the key factor for complete direct oxidation of borohydride. This study is focused on the synthesis of the nitrogen-doped carbon (N-doped C) catalysts supported Au-M (M = Co, Ni, Cu) nanoparticles using a rapid microwave heating method with the aim to use them as the anode material for DBHPFC. The electrocatalytic activity of the prepared M/N-doped C and Au-M/N-doped C catalysts for the borohydride oxidation reaction (BOR) was evaluated using cyclic voltammetry and chronoamperometry. The direct borohydride-hydrogen peroxide fuel cell was assembled using Pt as the cathode and the prepared M/N-doped C and Au-M/N-doped C catalysts as the anodes. The performance of a DBHPFC operating with 1 M NaBH4 + 4 M NaOH as fuel and 5 M H2O2 + 1.5 M HCl as an oxidant was investigated at different temperatures. It has been determined that the prepared Au-M/N-doped C catalysts have а higher activity and а better stability for the oxidation of borohydride compared to those of M/N-doped C (M = Co, Ni, Cu) catalysts. The direct borohydride-hydrogen peroxide fuel cell exhibited an open circuit voltage of cа. 1.8 V when the Au-M/N-doped C catalysts were assembled as the anodes.

Carbon-supported Pd-Co nanocatalyst as highly active anodic electrocatalyst for direct borohydride/hydrogen peroxide fuel cells

Pd/C and Pd-Co/C nanocatalysts are prepared via a simple and environmentally friendly method and are used as anodic catalyst for direct borohydride–hydrogen peroxide fuel cells. X-ray diffraction and transmission electron microscopy results indicate that Pd and Pd-Co nanoparticles adhere on carbon with the mean diameter of about 4 nm. The cyclic voltammetry, chronoamperometry, chronopotentiometry, and rotating disc electrode voltammetry results show that the electrocatalytic activity of Pd-Co/C is higher than that of Pd/C, especially Pd67Co33/C which shows the highest electrocatalytic activity for BH4− electro-oxidation with the electron-transfer number of 4.9 related to BH4− electro-oxidation reaction. The single direct borohydride–hydrogen peroxide fuel cell with Pd67Co33/C anode obtains the maximum power density as high as 66.84 mW cm−2 at 25 °C.

Enhancement of output power density and performance of direct borohydride-hydrogen peroxide fuel cell using Ni-Pd core-shell nanoparticles on polymeric composite supports (rGO-PANI) as novel electrocatalysts

In this research work, Ni-Pd nanoparticles with core-shell structure (CNi-SPd) were synthesized on different catalyst supports such as reduced graphene oxide (rGO), pure polyaniline (PANI) and polymeric composites of rGO with PANI (rGO-PANI) for the first time. In polymeric composite supports, the ratio of rGO to PANI was altered (0.36, 0.14 and 0.11). That way, after chemical reduction of graphene oxide to rGO with sodium borohydride, different polymeric composite supports of rGO-PANI were prepared by chemical oxidation of different amounts of aniline monomer with ammonium persulfate (APS) in rGO dispersions and named as rGO-PANI1 (rGP1), rGO-PANI2 (rGP2) and rGO-PANI3 (rGP3). X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), energy-dispersive X-ray spectroscopy (EDX), transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HR-TEM), fourier transform infrared (FT-IR) spectra, inductively coupled plasma mass spectrometry (ICP-MS) analysis and X-ray photoelectron spectrometer (XPS) were employed to study the morphology and crystal structure of the novel nanostructures. Catalytic behavior of the catalysts respect to NaBH4 oxidation was evaluated in half-cell configuration and in direct borohydride-hydrogen peroxide fuel cell. The cyclic voltammetry results showed that CNi-SPd/rGP1 has the highest borohydride oxidation current density (42678 A. g−1) respect to CNi-SPd/PANI (17072 A. g−1), CNi-SPd/rGO (39085 A. g−1), CNi-SPd/rGP2 (32260 A. g−1) and CNi-SPd/rGP3 (24954 A. g−1). As well as, the single fuel cell studies indicated that with CNi-SPd/rGP1 as anodic electrocatalyst, power density (339.10 mW.cm-2) was enhanced as 64.54% and 8.52% in comparison with CNi-SPd/PANI (120.23 mW.cm-2) and CNi-SPd/rGO (310.20 mW.cm-2), respectively. Theses consequences imply that the rGP1 polymeric composite with the ratio of rGO/PANI = 0.36 is a suitable support substance that can improves the electroactivity for borohydride oxidation considerably.

Application of platinum-cobalt-boron as the anode material for sodium borohydride-hydrogen peroxide fuel cells

The electroless deposition and galvanic displacement methods were used for the fabrication of cobalt–boron (CoB) catalysts modified with small amounts of platinum crystallites in the range of 9.8 to 14.4 μgPt cm–2. The prepared catalysts were studied as the anode materials for direct borohydride–hydrogen peroxide (NaBH4/H2O2) fuel cells at temperatures of 25–55°C. Polarization curves have been recorded with the aim to evaluate the fuel cell performance using the prepared CoB and that modified with Pt crystallites as the anode catalysts. For all catalysts (pure CoB and PtCoB) investigated, the peak power density values increase consecutively with the increment in temperature from 25°C up to 55°C. The values from 86–146 mV cm–2 and 146–234 mV cm–2 were determined for pure CoB and PtCoB catalysts, respectively. The highest specific peak power density of 21.5 kWgPt–1 was achieved at 55°C temperature when the PtCoB catalyst with the Pt loading of 9.8 μgPtcm–2 was employed as the anode catalyst in the NaBH4/H2O2 single fuel cell.

Smooth and Fiber-Shaped Co Coatings Decorated with Pt Crystallites As the Anode Catalysts for Direct Borohydride-Hydrogen Peroxide Fuel Cells

In the present work, the smooth and fiber-shaped Co coatings decorated with Pt crystallites were investigated as the anode material in direct borohydride-hydrogen peroxide fuel cells (DBHPFCs). The Co sublayers, which have different structures, e.g. smooth and fiber-shaped, were used as a substrate for the depositing of Pt crystallites. The Co layer having smooth structure was deposited on the Cu surface (denoted as Cosmooth/Cu) via electroless deposition using morpholine borane as a reducing agent. Co layers, which have a fiber-shaped structure and the thickness of ~3 mm, were electroplated on the Cu surface (denoted as Cofiber/Cu) from the electrolyte containing CoSO4, NaOH and N-(2-Hydroxyethyl) ethylenediamine. The Pt crystallites were deposited on the Cosmooth/Cu and Cofiber/Cu electrodes by their immersion into a Pt(IV)-containing solution at a temperature of 25oC for different time periods. It has been determined that the Pt loadings were in the range from 10 to 14 µgPt cm–2 and 5 to 29 µgPt cm–2 in the PtCosmooth/Cu and PtCofiber/Cu catalysts, respectively. The activity of the prepared PtCosmooth/Cu and PtCofiber/Cu catalysts for borohydride oxidation reaction (BOR) was evaluated using cyclic voltammetry and chronoamperometry. The performance of a DBHPFC operating with 1 M NaBH4 + 4 M NaOH as fuel and 5 M H2O2 + 1.5 M HCl as an oxidant, while employing Pt as the cathode catalyst and PtCosmooth/Cu and PtCofiber/Cu catalysts with different Pt loadings as the anodes were investigated. It has been determined that the prepаred PtCosmooth/Cu and PtCofiber/Cu cаtаlysts hаve а higher аctivity аnd а better stаbility for the oxidаtion of BH4 - compаred to those of Cosmooth/Cu аnd Cofiber/Cu. The аssembled direct borohydride-hydrogen peroxide fuel cell with PtCosmooth/Cu and PtCofiber/Cu cаtаlysts as the anodes exhibited аn open circuit voltаge of cа. 1.9 V.
