Improvements in the activity and stability of catalysts for oxygen reduction reactions are needed to make low-temperature, polymer electrolyte membrane fuel-cells viable for mobile applications. Pt3Sc and Pt3Y are shown experimentally to have greater catalytic activity than pure Pt after being identified through computational investigation of Pt- and Pd-based alloys.
