HydroX-Cell (S)™

HydroX-Cell(S)TM is AFC Energy’s latest generation hydrogen power generation technology.

Through adoption of our new, industry leading Anionic Exchange Membrane (AlkaMemTM), the HydroX-Cell(S)TM offers a current density repeatedly demonstrated to achieve levels equal to or greater than alternative high-power density cells in the market today.

This power density is achieved without the need for costly ultra-high purity (99.999%) hydrogen – a standard currently demanded by the world’s leading Proton Exchange Membrane (PEM) fuel cell technologies.

Superior power density, and therefore reduced footprint, opens further market opportunities for the Alkaline Fuel Cell not previously seen, including adoption in mobile applications such as trains, heavy machinery, shipping and associated military functions.

Good progress is being made in its development, strengthened by the launch of a world class AEM fuel cell testing and diagnostic facility in the UK in early 2021.  Read more on the S-Cell’s progress here.

The benefits of the HydroX-Cell(S)TM, compared to competing high power density fuel cells on the market, include:

  • Lower cost membrane technology
  • Ability to accept lower grade hydrogen
  • Equivalent or enhanced power density compared to PEM fuel cell
  • Zero greenhouse emissions
  • Low noise and odour
  • Same high alkaline fuel cell efficiency as HydroX-Cell(L)

The benefits of the HydroX-Cell(S)TM have been demonstrated at AFC Energy’s research facilities and are a prime focus of development activities at present.

The HydroX-Cell(S)TM  is currently undergoing development but is expected to be configured as:

  • 10kWel stack for integration into third party applications as a primary or auxiliary power source; and
  • A MegaBoxTM configuration with a market leading 2MW of power density set for deployment within a 40’ ISO container for stationary off-grid power demands.


Other bespoke sizing options are available if required.

Auxiliary Equipment for hydrogen generation equipment (ammonia crackers, electrolysers powered by renewable energy sources) are also available from third party suppliers through AFC Energy for integration into the final product solution.

Partners are invited to express interest in HydroX-Cell(S)TM applications for joint development or licensing arrangements.
