Key Points

The aim is to evaluate the effects of selected plasma treatment on transport properties in catalyst layers for water electrolysis.
Applied O2 plasma treatment to selectively remove surface ionomer aggregates.
Analyzed the interfacial contact resistance between accelerator layers and proton transport layers.
Significant reduction in interfacial contact resistance observed post-treatment, improving transport efficiency.
