A proton exchange membrane (PEM) electrolyzer produces hydrogen gas by electrolyzing a polymer membrane and using it as an ion conductor. Applications for this kind of electrolyzer include industrial operations, renewable energy storage systems, and fuel cell cars. Proton exchange membranes, bipolar plates, electrodes, and gas diffusion layers are the main parts of a PEM electrolyzer. Ions are carried by the proton exchange membrane, which keeps out electrons and other ions while permitting protons to flow through. In fuel cells and electrolyzers, a membrane electrode assembly (MEA) is a stack of constructed proton-exchange membranes (PEM) or alkali anion exchange membranes (AAEM), catalyst, and flat plate electrode. The expanding hydrogen economy is driving the market for PEM electrolyzers and MEA components, particularly for FCEVs and clean industrial operations.
