Solvay Aquivion® is a perfluorosulfonic acid (PFSA) ionomer membrane used to separate the anode and cathode compartments. Those ionomer membranes are melt-extruded products based on the unique Short Side Chain copolymer of Tetrafluoroethylene (TFE) and Sulfonyl Fluoride Vinyl Ether (SFVE) F2C=CF-O-CF2CF2-SO2F produced by Solvay. The key advantages are: (a) a very high concentration of functional groups for strong proton (or Na+, K+, Li+, etc.) conductivity, (b) a high softening point for high-temperature operation well above 80 ºC, and (c) strong water retention for better fuel cell operation at low-humidity conditions.
Aquivion® E98-15S is a good alternative to Nafion 117, even though it is slightly thicker. Aquivion® E98-09S is a good alternative to Nafion 115, while Aquivion® E98-05S can be used to replace Nafion 211 and 112.

Application Note:
Aquivion® membranes are typically used for unpressurized or pressurized H₂/Air proton exchange membrane fuel cells, unpressurized or pressurized H₂/O₂ proton exchange membrane fuel cells, unpressurized or pressurized water electrolyzers, unpressurized or pressurized electrochemical hydrogen pumps, redox flow batteries, pervaporation or gas humidification systems, etc., direct methanol fuel cells, direct ethanol fuel cells, and various other alcohol-based fuel cells can also benefit greatly from this cation exchange membrane.
