General description
Aquivion® PFSA ionomer membranes are melt-extruded films based on the short-side-chain (SSC) copolymer of Tetrafluoroethylene and the Sulfonyl Fluoride Vinyl Ether (SFVE) F2C=CF-O-(CF2)2-SO2F industrially produced by Solvay Specialty Polymers. Following a film hydrolysis the perfluoropolymer′s functional groups are operative in their sulfonic acid form, SO3H.
Application
Aquivion® PFSA membranes are used for electrochemical applications such as, but not limited to, polymer electrolyte fuel cells, electro-deionization systems, ozone generators, water electrolyzers, hydrogen separators and compressors, redox flow batteries as well as pervaporation or gas humidification systems.
