Hierarchically Porous Co-N-C Electrocatalysts with Enhanced Mass Transport and Cobalt Utilization Efficiency for Oxygen Reduction Reaction in High-Performance PEMFCs

Cobalt-coordinated nitrogen-doped carbon (Co-N-C) materials have emerged as promising alternatives to platinum-based catalysts for proton exchange membrane fuel cells (PEMFCs) due to their cost-effectiveness and durability. However, conventional Co-N-C catalysts...
