Unveiling the Structure‐Performance Relationship in Ruthenium‐Based Anode Catalysts for PEM Water Electrolyzers
ABSTRACT Ruthenium (Ru) based electrocatalysts are considered cost‐effective alternatives to expensive iridium (Ir)‐based anode catalysts in proton exchange membrane water electrolyzers (PEMWEs), due to their lower cost and high catalytic activity. However, these catalysts suffer from poor stability mainly due to metal...
