Designing fuel cell catalyst support for superior catalytic activity and low mass-transport resistance. [PDF]

Nat Commun, 2022
The development of low-Platinum content polymer electrolyte fuel cells (PEFCs) has been hindered by inexplicable reduction of oxygen reduction reaction (ORR) activity and unexpected O2 mass transport resistance when catalysts have been interfaced with ...
