The XION AEM-DURION-G2 membrane is a composite anion exchange membrane (AEM) that uses the Durion Gen2 resin as the polymer backbone with a hybridized imidazole side chain as its functional group and has an ion exchange capacity of 2.1 – 2.5 mequiv/g. Durion Gen2 membranes offer excellent mechanical strength and stability to a wide variety of chemistries. Xergy currently produces Durion Gen2 anion exchange membrane sheets in 5, 10, 20, and 30µm thicknesses and 5x5cm, 10x10cm, and 15x15cm sizes. The image shows the chemical composition of the anion exchange resin used to manufacture Xion Composite Durion Gen 2 membranes.

The XION AEM-DURION-G2 can be used in fuel cells, electrolyzers, electrodialysis, redox flow batteries, electrochemical compressors, and a wide variety of other devices.

XION Composite Durion Gen2 AEMs are ultra-thin, ultra-strong, provide ultra-high performance for various alkaline chemistry-based applications. The ionomer structure contains a polyphenylene backbone with a hybridized imidazole side chain for its functional groups. A reinforcement layer is integrated into the membrane structure to provide enhanced mechanical properties, which is composed of microporous ePTFE (also known as expanded PTFE). The enhanced mechanical properties as free-standing membranes, providing higher ionic conductance without sacrificing strength.
