PEM Technology

PEM technology uses solid polymer electrolytes to separate electrode gases,

Water molecules form oxygen and protons at the anode, electrons travel through an external circuit, and protons pass through the proton exchange membrane to the cathode, combining with electrons to produce pure hydrogen gas.

PEM electrolyzers can be used for the electrolysis technology that produces high-purity hydrogen.
