Abstract: The domestic and foreign application and demonstration cases of PEM (proton exchange membrane) water electrolysis for hydrogen production are introduced. Combining with the future development trend of renewable energy power generation, the application direction and prospect of PEM water electrolysis for hydrogen production under the goal of "double carbon" are analyzed. At the same time, the research progress of key materials and components such as anode catalyst, proton exchange membrane, membrane electrode, current collector and bipolar plate of PEM water electrolysis stack is reviewed. The future development routes of low iridium anode catalyst, non-iridium and low Pt cathode catalyst are described in detail. The main problems and the development direction of PEM water electrolysis for hydrogen production in the future are summarized.

Key words: proton exchange membrane, water electrolysis, green hydrogen, carbon emission reduction, carbon neutrality, membrane electrode assemble, bioplate, current collector
