Exploring ionomer distribution strategies within catalyst layers for high-performance proton exchange membrane fuel cells

Proton exchange membrane fuel cell (PEMFC) performance is strongly affected by ionomer distribution within catalyst layers (CLs). In this study, five catalyst-coated membrane (CCM) configurations, with additional ionomer layers, uniform ionomer distribution, and gradient ionomer...

Unveiling the Structure‐Performance Relationship in Ruthenium‐Based Anode Catalysts for PEM Water Electrolyzers

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 poo...
