For polymer electrolyte fuel cell (PEFC) electrocatalysts, carbon corrosion is one of the important technological issues to be solved. TiO₂ is a possible alternative support material. In this study, vaporgrown carbon fiber (VGCF-H) conductive fillers are applied as the built-in electron-conductive backbone, on which Nb-doped TiO₂ is coated and Pt nanoparticles are then impregnated. FESEM images of Pt/Ti_0.95Nb_0.05O₂/VGCF-H reveal selective impregnation of Pt nanoparticles on the TiO₂ grains rather than the VGCF-H conductive fillers. This conductive-filler-integrated electrocatalyst exhibits relatively higher electrochemical surface area (ECSA) and oxygen reduction reaction (ORR) activity, compared to the electrocatalysts without conductive fillers.
