XION Composite NAFION Membranes are ultra-thin, highly conductive, and highly stable reinforced proton exchange membranes (PEM). The membrane is based on a perfluorosulfonic acid (PFSA) ionomer developed by Chemours. NAFION has been manufactured for over 40 years and is the most robust PFSA ionomer on the market with the long side chain and durable end group capping. A reinforcement layer is integrated into the structure of the membrane to provide enhanced mechanical properties. The enhanced mechanical properties allow Ultra-thin, Ultra-Strong, and Ultra-High-Performance free-standing membranes, i.e. providing higher ionic conductivity without sacrificing strength. Applications for XION Composite NAFION Membranes include fuel cells, electrolyzers, and sensors. XION Composite NAFION Membranes are available in two variations based on the equivalent weight (EW) of the ionomer. 1000EW has slightly higher ionic conductivity, but 1100EW has slightly greater stability.
