Proton Exchange Membrane (PEM) for hydroelectrolysis is one of the core components of PEM hydroelectrolysis hydrogen production equipment. It plays the main functions of Proton conduction, electron isolation and hydrogen/oxygen blocking, and determines the performance and life of PEM hydrolysis hydrogen production equipment.It can be used in energy,chemical industry,smelting and other fields.Hydro-electrolysis series of proton crosslink membranes are based on chemically stable non-enhanced perfluorinated ion exchange membrane products,whose structure is a single component layer of perfluorinated sulfonate resin(FIG.1),which has a compact structure.
