Membrane

Nafion™ membranes are proton-conductive polymer film, also known as electrolyte or ionomer, that allow only protons to cross-over, the key function of Nafion™ proton exchange membrane fuel cells and water electrolyzers.

Chemour's Nafion™ PFSA membranes are non-reinforced films based on Nafion™ PFSA polymer, a perfluorosulfonic acid/PTFE (polytetrafluoroethylene) co-polymer 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.
