Ion Proton Exchange Membrane Perfluorosulfonic Acid Membrane Nafion N117

      Nafion PFSA membranes are non-reinforced films based on Nafion PFSA polymer, a perfluorosulfonic acid/PTFE copolymer in the acid (H+) form. Nafion PFSA membranes are widely used for Proton Exchange Membrane (PEM) fuel cells and water electrolyzers. The membrane performs as a separator and solid electrolyte in a variety of electrochemical cells which require the membrane to selectively transport cations across the cell junction. The polymer is chemically resistant and durable.
