Principles of PEM water electrolysis for hydrogen production:

PEM water electrolysis for hydrogen production refers to the proton exchange membrane water electrolysis for hydrogen production, of which the process involves a proton exchange membrane as a solid electrolyte and pure water as the raw material for hydrogen production from water electrolysis. Compared with the alkaline water electrolysis technology for hydrogen production, PEM water electrolysis technology for hydrogen production is superior for its large current density, high purity of hydrogen, and fast response speed.
