Audited Supplier Introduction:Our perfluorinated ion membrane GK® N-11 series is a single-component perfluorosulfonic acid H-type perfluorinated ion membrane produced by the steel tape casting method. Perfluorinated ion membranes are used as solid electrolytes to separate the anode and cathode in various electrolytic cells and batteries. The membrane has the property of one-way cations. Due to the use of polytetrafluoroethylene as the main chain, the most suitable molecular weight and ion exchange can be adjusted Capacity, the membrane has the characteristics of chemical resistance and durability. Widely used in: vanadium batteries, flow batteries, fuel cells, hydrogen production by electrolysis of water and other fields.
