Professional Perfluorinated Ion-Exchange Membrane(PIEM) and Homogeneous Ion-Exchange Membrane manufacturer in China

Ion exchange membrane for hydrogen fuel cell

The Perfluorinated sulfonic acid ion exchange membrane and proton exchange membranes are produced with the new casting method, the casting process can be combined with doping technology,for the hydrogen fuel cell, we add EPTFE(expanded polytetrafluoroethylene) microporous reinforcing material to the traditional proton exchange membrane, which has the characteristics of high strength, high conductivity, and low ion permeability, and so on.
