Nafion Membrane is 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 Membranes with low thickness are additionally reinforced to maintain mechanical stability. Available grades: Nafion 211 and Nafion 115.

Application note
Nafion 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. The membrane is protected from both sides by a white foil, which should be removed before the usage.
