Fuel Cell Earth Nafion Membrane N117 15cm x 15cm  DFS Item

Manufacturer:  Fuel Cell Earth N11715

•7 mil, (Thickness, Note: 1 mil = 25.4 microns )•Product cut to dimension +/- 1% at 50% RH. 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 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 that require the membrane to selectively transport cations across the cell junction. The polymer is chemically resistant and durable.
