Specifications

Untreated Nafion 212 Membrane used to separate the anode and cathode compartment of PEM fuel cells and water electrolyzers.

Untreated Nafion 212 is 50.8 micrometers (2 mil) thick. The membrane is positioned between a backing film and a coversheet.

DuPont™ Nafion® 212 membranes are based on chemically stabilized perfluorosulfonic acid/PTFE copolymer in the acid (H+) form, and 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.
