The XION™ PEM-DYNENO is a composite PEM that uses the 3M Dyneon™ resin. It is stable under acidic and neutral conditions. This membrane can be used in fuel cells, electrolyzers, electrodialysis, redox flow batteries, electrochemical compressors, and a wide variety of other devices. All Xion™ membranes have high selectivity, high chemical resistance, and durability. The image shows the chemical composition of the Dyneon resin. The Xion™ PEM-Dyneon is a reinforced composite ion exchange membrane that provides excellent mechanical strength and stability to a wide variety of ionomer chemistries.
