Key Points

This research aims to explore how interfacial control can optimize the architecture of catalyst layers in PEMFCs for better performance.
Investigated the role of interfaces in proton transport, gas diffusion, and water management within PEMFCs.
Analyzed the effects of advanced catalyst layer designs on power output and durability in controlled settings.
Enhanced interfacial control increased power output by 15% compared to conventional designs (p<0.01).
Optimized water management improved durability by reducing performance degradation by 20% over 1000 cycles.

Abstract

Interfaces within polymer electrolyte membrane fuel cells (PEMFCs) dictate proton transport, gas diffusion, and water management -processes that ultimately control power output, efficiency, and durability. Conventional catalyst layers neglect these...
