This paper reports new findings of an investigation of the electrocatalytic performance of nanostructured PtVFe catalysts in proton exchange membrane fuel cells (PEMFC). The membrane electrode assembly was prepared using nano-engineered PtVFe nanoparticles with controlled composition and size supported on carbon as the cathode electrocatalysts. The results reveal that the PtVFe/C catalysts exhibited excellent fuel cell performance, better than that using the commercial Pt/C catalyst. This finding provides the first example demonstrating the viability of the PEMFC application of the nanostructured trimetallic catalysts.
