Ion-exchange membranes replacing fluorinated polymers (PFCs)


Summary

Ionomr has developed an ion-conductive membrane with the broadest chemical and mechanical stability available. The membranes are made from hydrocarbon polymers without any PFCs added. The most widely-used membranes today are perfluorinated and these are non-recyclable and generates bio-accumulative toxic waste. The hydrocarbon-based materials include Aemion™, the most durable and high-performance anion-exchange membrane (AEM) product on the market. 

Aemion™ applications cover hydrogen and renewable fuels in AEM water electrolysis, AEM fuel cells and conversion of CO2; industrial applications of salt splitting recovery of acids & metals; and advanced battery solutions for lithium-sulfur, metal-air, nickel-metal hydride, and flow batteries. 


Description

Aemion™, is stable in both highly basic and strongly acidic environments, providing an improvement in the product life cycle, even in the harshest operating conditions. This unique stability unlocks a broad range of applications from industrial water treatment, chemical generation and recovery, long-life storage, and hydrogen production. Aemion is based on the breakthrough discovery that weak sites in polymer structure are the root cause of AEM instability, and they can be effectively protected to prevent alkaline and oxidizing species from breaking down the polymers.

 

Key benefits:

  • Stable: Chemically and oxidatively stable across a wide range of operating conditions - provides strong alkaline functionality (>2M @ 60ºc) in addition to acidic stability for use in the harshest of applications.
  • High Strength: Strongest unsupported materials on the market for ease of handling, longer life, and thinner membranes, resulting in low ionic resistance.
  • Performance: High conductivity at both room and elevated temperatures to enable low resistance applications with higher current densities.
  • Processable: Soluble polymer in low-boiling solvents, allowing simple and consistent integration into existing product platforms as a strong industrial coating. Can be used as a stable, ion-conductive catalyst binder and enables coated, 3D electrodes.
  • Green: reduces the environmental impact through its entire lifecycle. Free from PFCs.
