Nafion™ 117
Price:
From $33.00
Nafion™ Membrane is used to separate the anode and cathode compartment of Proton Exchange Membrane fuel cells and water electrolyzers. The thickness of this particular cation exchange membrane, Nafion™ 117 makes it suitable for Direct Methanol Fuel Cells (DMFC). Nafion™ 117 is 183 micrometers (7.2 mil) thick.
Chemours (formerly 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.
