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.

Packaging

Membranes are packed and sealed in a barrier protection pouch inside a cardboard box to prevent damage or deterioration. It is recommendable storing the product in a clean, humidity-controlled environment protected from direct sunlight or other sources of irradiation or heat. Sheet dimensions are based on product conditioned at 23°C and about 50% relative humidity. They may slightly vary upon exposure to different ambient conditions. Maximum temperature rating is 230°C, overheating will result in polymer degradation, discoloration and release of toxic volatile decomposition product.

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.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
