Findings reveal how secondary nitrogen precursors affect catalyst performance in proton exchange membrane fuel cells, suggesting efficient alternatives to platinum-based catalysts.
Proton exchange membrane fuel cells (PEMFCs) offer high efficiency, rapid refueling, and zero-carbon operation, but commercialization is constrained by the cost of platinum-based oxygen reduction catalysts. Transition metal-nitrogen-carbon materials, particularly...
