The XION PEM-NAFION is a composite proton exchange membrane that uses the Nafion resin. It is stable under acidic and neutral conditions. This membrane can be used in fuel cells, electrolyzers, electrodialysis, redox flow batteries, electrochemical compressors, sensors, and a wide variety of other devices. All Xion™ membranes have high selectivity, high chemical resistance, and durability.

The XION PEM-NAFION is a reinforced composite ion exchange membrane that provides excellent mechanical strength and stability to a wide variety of ionomer chemistries.  The mechanical reinforcement is the microporous expanded PTFE matrix, which has excellent thermal, chemical, and mechanical stability under various conditions.

XION 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.

Benefits of Xion Composite Nafion Membranes:

-High proton or cation conductivity
-Great chemical stability at low and high temperatures
-Ultra-thin membranes with excellent mechanical strength
