PGM-free Electrodes for AEM and Alkaline Electrolysis - Catrode®

  • With Latent Drives' innovative electrochemical treatment process, they activate stainless steel electrodes to make Catrodes® which combine both catalyst and electrode as one homogeneous part, without additional ingredients.
  • Catrodes are PGM-free (Platinum Group Metal) robust high-performance products.
  • The production process is developed for high volume mass production at realistic costs – reducing the capital costs of Green Hydrogen.
  • The Catrode is a Ni-Fe catalyst. First, the electrochemical surface area is increased then chromium is removed, and nickel is migrated and exposed on the surface of the stainless steel felt to produce a nickel iron catalytic surface layer.
  • The catalyst layer is formed on stainless steel felt which acts as both the Catalyst, Electrode and Gas diffusion layer combined.
  • Catrodes are 0.6mm thick with an active area of 200 cm² as standard but different thickness and areas could be treated as a custom request.
  • PGM free Catrodes performance in OER is comparable with state-of-the-art precious metal catalysts such as platinum and iridium and significantly surpasses the performance of nickel electrodes at a much-reduced cost.
  • Catrodes exhibit a stable performance below 1.58V RHE at 0.2A/cm2 at 50°C for 22 hours run in an ElyFlow test cell with an active area of 10 cm² compared to the overpotential of a commercially available Catalysed Nickel foam which reached 1.69V RHE.
  • The PGM-free Electrodes are designed to be run wet i.e. with liquid electrolyte in contact with the Catrode and membrane. Not intended for use with Nafion membranes.

Application areas

  • For alkaline water electrolysis, with either AEM or Zero Gap designs.
  • For use with Potassium Hydroxide (KOH) electrolyte in concentrations from 01.M to 5M.
  • Catrodes were developed to be used as anodes but can also be used as cathodes in an alkaline electrolyser.
  • Catrodes may also have potential to be used in batteries and fuel cell technology but after mutual collabaration with Latent Drive.

Use cases

  • Catrodes are being used as the combined gas diffusion layer and catalyst in a European electrolyser startup.
  • Catrodes in the form of treated stainless steel sheet is also being developed for a customer.
