Plastic polymer Nafion® N-117 PFSA DuPontTM, universally used as an electrolyte base for ionic exchange of PEM (Proton Exchange Membrane) fuel-cells and electrolysers, is a simple transparent membrane. Thus 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.

It's a thin transparent plastic film able to transport  H+ ions through the polymer structure and N-117 features a thickness of 183um.

Thanks to its high thickness this product is particularly indicated for MEA manufacturing to be used with methanol and formic acid fuels.

Available in different shapes and sizes with the possibility to have free of charge customizations on needs. Typical dimensions of sheets on stock are:
