Developed initially for the HydroX-Cell(S)TM  fuel cell system, AFC Energy’s leading AlkaMemTM Anionic Exchange Membrane (“AEM”) offers a highly conductive, robust and cost-effective membrane technology for sale or licensing into ancillary market applications.

AlkaMemTM applications include:

  • Alkaline Water Electrolysis
  • Alkaline Fuel Cells
  • Fuel Synthesis
  • Electrodialysis
  • Desalination
  • Acid Remediation
  • Salt Water Batteries
  • REDOX Flow Batteries

The market for highly conductive and stable membrane technologies continues to grow and presently exceeds $1 billion. The performance of the AlkaMemTM has been independently monitored and successfully appraised by industry leaders against key operational metrics. The market introduction will increase customer choice and we expect to be competitive on price and performance.

The AlkaMemTM membrane is available for license and joint development applications in various thicknesses. The table below provides details of the key technical specification that AlkaMemTM can provide.
