South Korean scientists develop novel protection layer for cheaper electrolyser catalysts

Scientists from the Gwangju Institute of Science (GIST) in South Korea have developed a novel protection layer for electrolyser catalysts that could reduce the cost of green hydrogen production.

H2 View understands the layer made of tetraphenylporphyrin (TTP) has been designed for use with nickel-iron (Ni-Fe) catalysts on electrolyser anode to prevent corrosion.

The GIST scientists says Ni-Fe catalysts are a cost-effective, potential solution to expensive electrolyser catalyst costs, however, are prone to corrosion, causing deactivation due to oxygen released at the anode.
