The research aims to design an efficient cathode catalyst with high activity and durability for proton exchange membrane fuel cells.
Developed a hybrid intermetallic Pt2CoNi/C catalyst using a one-step molten salt synthesis method.
Characterized the catalyst's unique surface structure and facets.
Evaluated performance in a proton exchange membrane fuel cell at 60 °C.
Achieved peak power densities of 0.92 W cm–2 in H2/O2 and 0.70 W cm–2 in H2–air operation.
Maintained electrochemical performance after 50,000 potential cycles.
Higher ORR onset potentials observed at ordered–disordered interfacial sites, indicating optimized adsorption.
