Reducing the Demand for Precious Metals in PEM Water Electrolysis

Uncoated Electrolyser components severely degrade in performance due to the acidic and oxidative environments of PEM Water Electrolysers (PEMWE).

 

Gold, Platinum or Iridium-coated Titanium electrodes are not sustainable in the long term due to cost and the sustainability of the material supply chain.
