Anion Exchange Ionomer Dispersion (Orion CM1) for Alkaline Electrolyzer and Fuel Cell, 10 mL/bottle, CAEFCAEIDCM1

Orion TM1 is a high-performance Anion Exchange Ionomer (AEI) produced by Orion Polymer. It is based on a proprietary poly(phenylene) chemistry and is specifically designed to compete with the most stable materials on the market, such as PiperION and Sustainion.

The Orion ionomer stands out due to its ether-free, all-carbon backbone. This structure is a direct response to the "ether-death" problem, where the oxygen links in traditional polymers are cleaved by hydroxide ions (OH-). (1) Backbone with rigid poly(phenylene) structure. By removing ether (C-O-C) linkages, the material achieves remarkable stability in 1M KOH at temperatures up to 80°C. (2) Cationic Group: Typically utilizes high-stability quaternary ammonium or piperidinium groups.

The Orion CM1 ionomer is primarily used in the construction of Membrane Electrode Assemblies (MEAs) for: (1) AEM Water Electrolyzers (AEMWE): As a binder for non-precious catalysts like NiFe and Co3O4. Its high IEC allows for lower voltages at high current densities. (2) AEM Fuel Cells (AEMFC): Provides the necessary ionic conductivity in the catalyst layer while allowing water produced at the anode to escape. (3) Selective Separation: Used in electrodialysis and other desalination technologies where alkaline stability is required.
