Localized growth of Pt on Pd as a bimetallic electrocatalyst with enhanced catalytic activity and durability for proton exchange membrane fuel cell

Journal Article


Abstract


  • Pt on Pd nanocatalyst with hollow interior structure was synthesized by a modified galvanic replacement method. The hollow nanoparticles with rough Pt surface on Pd layer (Pt–Pd) exhibit significantly higher electrochemically active surface area when compared to that of conventional hollow Pt nanoparticles, with remarkably enhanced oxygen reduction reaction activity and durability compared to those of as-synthesized hollow Pt catalysts and the E-TEK commercial Pt/C. Real-world application of the catalysts in a single fuel cell has been evaluated and found consistent with the electrochemical measurements.
