Nafion Membrane NRE-211
Nafion® Membrane NRE-211, 1 mils
•1 mil, (Thickness, Note: 1 mil = 25.4 microns )
•Product cut to dimension +/- 1% at 50% RH
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.
