XION Composite DURION Membranes are ultra-thin, ultra-strong, provide ultra-high performance and have demonstrated excellent chemical stability as a reinforced anion exchange membrane (AEM). The ionomer structure contains a polyphenylene backbone with quaternary ammonium functional groups. A reinforcement layer is integrated into the structure of the membrane to provide enhanced mechanical properties. The enhanced mechanical properties as free-standing membranes, providing higher ionic conductance without sacrificing strength. Applications for XION Composite DURION Membranes include fuel cells, electrolysis, and flow batteries. The DURION™ TM1 ionomer has demonstrated exceptional stability and as reported in a blind study conducted at NREL [1].
