PEM hydrogen production selects the perfluorosulfonic acid proton exchange membrane. It has good chemical stability, proton conductivity, and gas separation. As a solid electrolyte to replace asbestos membrane, it can effectively block electron transfer and improve electrolyzer safety. The main components of PEM water electrolyzer are proton exchange membrane, cathode catalytic layer, cathode gas diffusion

According to Salzgitter Mannesmann Forschung, the electrolyzer broke through to produce 200Nm³ of green hydrogen for titanium felt per hour for the first time, and the project was able to demonstrate 84% power efficiency (LHV, net thermal efficiency). This is an unprecedented high efficiency. In contrast, electrolysis techniques such as alkaline or PEM (proton exchange
