Sustainable electricity generation via hydrogen fuel cells requires the development of efficient oxygen reduction reaction (ORR) catalysts. In situ/operando experiments are necessary to uncover the extent of dynamic material changes during catalysis. Herein, we use in situ/operando X-ray absorption...
