一般說明

Aquivion® PFSA dispersions are based on the short-side-chain (SSC) copolymer of Tetrafluoroethylene and the Sulfonyl Fluoride Vinyl Ether (SFVE) CF2=CF2-O-(CF2)2-SO2F industrially produced by Solvay Specialty Polymers. The resulting perfluoropolymer′s functional groups are in their sulfonic acid form, SO3H.

應用

Can be used as a formulation additive for production of polymer electrolyte fuel cell electrodes, manufacture or repair of cation-exchange membranes, surface coatings of PTFE membranes to improve their wetting behavior or for the development of superacid catalysts. Addition of further film-forming and/or other volatile or non-volatile chemicals is necessary to impart the desired processing and end-product characteristics.

Perfluorosulfonic Acid Membranes for Fuel Cell and Electrolyser Applications

Advances in the electrochemical conversion of water to and from hydrogen and oxygen have principally been achieved through the development of new materials and by understanding the mechanisms of the degradation of proton exchange membrane fuel cells (PEMFC) during operation.
