Membrane
A proton-conductive polymer film also known as electrolyte or ionomer, allows only protons to cross-over, the key function of proton exchange membrane fuel cells and water electrolyzers. Dupont 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.

Nafion - Model 117 - Fuel Cell Membrane
Untreated Nafion 117 is 183 micrometers (7.2 mil) thick. DuPont™ Nafion® 117 membranes are non-reinforced films based on chemically stabilized perfluorosulfonic acid/PTFE copolymer in the acid (H+) form. The physical properties remain the same for the chemically stabilized membranes, which exhibit substantially lower fluoride ion release compared to the non-stabilized polymer – a sign of improved chemical durability. Nafion PFSA ...

Nafion - Model XL - Fuel Cell Membrane
Untreated Nafion® XL at 27.5 micrometers(1.1 mil)thick. DuPont™ Nafion XL membrane is an extended-lifetime reinforced membrane based on chemically stabilized perfluorosulfonic acid/PTFE copolymer in the acid (H+) form. The reinforcement improves the membrane's handling and physical properties. When the reinforcement is combined with the chemically stabilized polymer, the membrane exhibits both substantially lower fluoride ion release and ...
