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™ 115 makes it suitable for Direct Methanol Fuel Cells (DMFC) and Electrolysis applications. Nafion™ 115 is 127 micrometers (5 mil) thick.Chemours (formerly DuPont) Nafion™ 115 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.

Nafion™ XL membranes are newly developed reinforced membranes that enhance the chemical stability of Nafion™ membranes. The mechanical durability and enhanced chemical stability of the Nafion™ XL membrane are the result of an advanced stabilization system that increases mechanical strength and provides resistance to peroxide attack, resulting in improved membrane life and performance. Nafion™ XL is 27.5 micrometers (1.1 mil) thick.
