PtNi-W/C with Atomically Dispersed Tungsten Sites Toward Boosted ORR in Proton Exchange Membrane Fuel Cell Devices
Highlights A hybrid electrocatalyst consisting of PtNi-W alloy nanocrystals loaded on carbon surface with atomically dispersed W sites was realized. Single-atomic W formed protonic acid sites and established an extended proton transport network at the catalyst surface. Peak power density is enhanced...
