Abstract
Physical chemical properties of Ce08Sm02IryCo1-yO3-ô (y = 0.03-0.04) and preliminary testing as cathode material for low-temperature SOFC
Highlights
Solid oxide fuel cells (SOFC) are electrochemical devices that generate electricity and give off heat as by-product
Jiang et al reported that an anode supported fuel cell with a cosynthesized 70 wt.% Sm0.5Sr0.5CoO3 – 30 wt.% Sm0.2Ce0.8O1.9 (SSC–SDC73) composite cathode exhibited a peak power density of 924 mW cm–2 at 800 °C.10
The results indicated that the cell with the inkjet printing cathode layer exhibited fantastic electrochemical performance, with a peak power density as high as 940 mW cm–2 at 750 °C.11
Summary
Solid oxide fuel cells (SOFC) are electrochemical devices that generate electricity and give off heat as by-product. SOFCs have attracted significant attention for several years, because of their high energy efficiency, excellent fuel flexibility, the growing global demand for non-polluting energy conversion systems, and a need for devices that can utilize renewable energy.[1,2,3,4] SOFC systems, those operating above 800 °C, have some disadvantages which include longer start-up and cool down times, specialised and expensive balance of plant material, thermal management issues, and degradation of cell and stack components. Jiang et al reported that an anode supported fuel cell with a cosynthesized 70 wt.% Sm0.5Sr0.5CoO3 – 30 wt.% Sm0.2Ce0.8O1.9 (SSC–SDC73) composite cathode exhibited a peak power density of 924 mW cm–2 at 800 °C.10 Li et al exploited the fabrica-
