Abstract
In order to increase the hydrogen production rate as well as ozone production at the anode side, increased voltage application and more catalyst utilization are necessary. The membrane electrode assembly (MEA) produces hydrogen/ozone via proton exchange membrane water electrolysis (PEMWE)s which gives priority to a coating method (abbreviation: ML). However, coating takes more effort and is labor-consuming. This study will present an innovative preparation method, known as flat layer (FL), and compare it with ML. FL can significantly reduce efforts and largely improve MEA production. Additionally, MEA with the FL method is potentially durable compared to ML.
Highlights
The greenhouse effect of this century is increasing and a reduction of carbon dioxide emission through various methods is the global consensus
A characteristic of the flat layer (FL) method is to form a loose interface between the anode and membrane to avoid change during wet-operation or dry-closedown of proton exchange membrane water electrolysis (PEMWE)
Is 10.3% lower compared to that of methods decline by 81% (ML). Both ML and FL exhibit a slow increase and stable state which proves the feasibility of FL
Summary
The greenhouse effect of this century is increasing and a reduction of carbon dioxide emission through various methods is the global consensus. Developing clean and renewable energy has been the main target until now. The major issue of renewable energy is the unstable output of power that is affected by seasonal and environmental factors, which results in electric grid management difficulties. The advantages of proton exchange membrane water electrolysis (PEMWE). As energy storage are its high current density, high purity gas production, and compact system. The membrane electrode assembly (MEA), including anode/electrolyte/cathode, is a key component of PEMWE. If the anode is composed of noble metal oxide-IrO2 , PEMWE produces hydrogen and oxygen at the cathode and anode side during the off-peak period for energy storage. The supply of stored hydrogen and oxygen gas for the fuel cell is used to generate power during the peak-hour period
