Evaluated Alternative Ion-exchange membranes replacing fluorinated polymers (PFCs) Ionomr has developed an ion-conductive membrane with the broadest chemical and mechanical stability available. The membranes are made from hydrocarbon polymers without any PFCs added. The most widely-used membranes today are perfluorinated and these are non-recyclable and generates bio-accumulative toxic waste. The hydrocarbon-based materials include Aemion™, the most durable and high-performance anion-exchange membrane (AEM) product on the market. Aemion™ applications cover hydrogen and renewable fuels in AEM water electrolysis, AEM fuel cells and conversion of CO2; industrial applications of salt splitting recovery of acids & metals; and advanced battery solutions for lithium-sulfur, metal-air, nickel-metal hydride, and flow batteries.
