The Nafion™ HP is an ultra-thin membrane that offers high power density. The membrane is reinforced and designed for lower relative humidity environments and high operating temperature.

Nafion is a perfluorosulfonic acid (PFSA) polymer developed by DuPont in 1966.1 The cation transport properties of Nafion are central to its use in diverse applications.

NafionTM membranes are made from ion exchange polymers. The perfluorinated polymer provides chemical and thermal stability similar to that of TeflonTM fluoropolymer resin.

The Nafion™ portfolio of membranes, dispersions, and resins provides leading-edge solutions for energy storage, fuel cells, hydrogen production, and ultra-high purity chemical production.

Since then, Nafion polymers have found wide application, especially in the chlor-alkali industry as membrane materials, but also, in more recent years, in proton exchange membranes in fuel cells.
