The XION AEM-DAPPION membrane is a composite anion exchange membrane (AEM) that uses the Dappion Gen1 resin (3-D polyphenylene) as the polymer backbone with a benzyl trimethyl ammonium side chain as its functional group and has an ion exchange capacity of 2.1 – 2.5 mequiv/g. Dappion Gen1 membranes offer excellent mechanical strength and stability to a wide variety of chemistries. Xergy currently produces Dappion Gen1 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 Dappion Gen1 membranes.

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