Impact of Transition Metals and Electrocatalyst Layer Thickness on the Pt‐Based Cathodes of Proton Exchange Membrane Fuel Cells – Do Multimetallic Electrocatalysts Necessarily Yield an Improved Performance? (Adv. Energy Mater. 25/2025)
Proton Exchange Membrane Fuel Cells Nonnoble transition-metals (TMs) in PtCuNi/C catalysts have a dual influence in proton-exchange membrane fuel cell cathode catalyst layer. While TMs act as a “sacrificial component” of PtCuNi/C, inhibiting Pt dissolution from the PtMx nanoparticles bearing the active sites, they promote the formation of separate catalysts and ionomer domains in the catalyst layer, inhibiting the interactions with the hydrophobic polytetrafluoroethylene backbones of the ionomer; this is detrimental to mass-transport phenomena that are crucial to minimize the overall proton exchange membrane fuel cell overpotential at large current densities.
