PEM electrolyzer 

Tne PEM electrolyzer has high current ensity and large active area.The scale of a single cell breaks through the MW level. It is small in size high in efficiency, high in hydrogen purity, and flexible in operation.It can be perfectly coupled with wind, light and other renewable energy sources.

It is mainly composed of an electrode and a proton exchange membrane. With pure water as the electrolyte, the water molecules are decomposed into H+ and O2 on the anode, and H+ passes through the membrane to the cathode, where H2 is generated.
