Ru-promoted Pt/C catalysts with different Ru/Pt ratios are prepared by selective chemical vapour deposition (CVD) of Ru onto a Pt surface. The optimum PtRu/C (Ru/Pt = 0.44) catalyst prepared using a CVD method shows improved performance as an anode for a polymer electrolyte membrane fuel cell in the...
