PEM water electrolysisproton exchange membranesstackSummary Proton exchange membrane (PEM) water electrolysis is considered one of the most promising technologies to produce hydrogen with a high degree of purity from renewable energy resources such as wind, photovoltaic, and hydropower. The process is ...
The operational conditions categorize the electrolytic water splitting. Polymer electrolyte membrane (PEM) electrolysis occurs within an acidic electrolyte using a proton exchange membrane to transport protons (H+). PEM electrolysis operates at temperatures of 50–80 °C, pressures of less than 30 bar,...
Coupled processes of heat and mass transfer, electric and ionic conduction, and mechanical stress take place over a wide range of length scales in a proton exchange membrane water electrolyzer (PEMWE). Modeling and simulating such systems can help elucidate these processes and provide guidelines for...
