Experiments reveal durability challenges of cathode catalysts in PEM fuel cells, highlighting improvements needed for the oxygen reduction reaction.
The sluggish oxygen reduction reaction (ORR) determines the performance and lifetime of Proton Exchange Membrane (PEM) fuel cells. The commercialized cathodic ORR catalyst is synthesized with platinum-group-metal (PGM)-based chemicals, which...
