The main components of PEM water electrolysis hydrogen production equipment are proton exchange membrane, anode and cathode catalytic layer, anode and cathode gas diffusion layer, anode and cathode, and end plate from inside to outside. The diffusion layer, catalytic layer, and proton exchange membrane form the membrane electrode, which is the main venue for material transportation and electrochemical reactions in the entire water electrolysis cell. The characteristics and structure of the membrane electrode directly affect the performance and lifespan of the PEM water electrolysis cell.
