Nafion™ Membrane NE1035 is used to separate the anode and cathode compartment of Proton Exchange Membrane fuel cells, batteries and water electrolyzers. Nafiion 1035 has a low Equivalent Weight (1000EW) and a higher conductivity, making it particularly suitable for energy storage applications, such as batteries, Direct Methanol Fuel Cells (DMFC) and Electrolysis applications. Nafion™ NE1035 is a 89 micrometer (3.5 mil) thick cation exchange membrane.

Chemours Nafion™ NE1035, EW1000 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.
