Key Degradation Mechanisms in PEM Water Electrolysis Summary In PEM water electrolysis technology, degradation at the anode (oxygen evolution side) is a critical bottleneck limiting electrolyzer lifespan and cost control. The two most pivotal degradation mechanisms are the dissolution of the platinum-coated titanium diffusion layer and the oxidation and dissolution of the iridium-based catalyst. The following section details these two mechanisms, their interrelationships, and potential mitigation strategies. I. [...]
