dc.description.abstract | In proton exchange membrane fuel cells, the utilization of supporting materials for Pt-based catalysts is an effective approach to improve the oxygen reduction reaction (ORR) performance. In this study, a doped porous carbon (DPC) as a support was prepared with polyaniline as the main carbon source, iron nitrate nonahydrate as a metal doping source, and dicyandiamide as a nitrogen doping source in the presence of 20 nm silica bead as a template. The carbon support showed fairly high specific surface area (similar to 740 m(2) g(-1)), well-defined pore structure, and a proper nitrogen doping (similar to 4.9 at.%). The Pt cathode catalyst deposited on the doped porous carbon using an NaBH4 reduction method (Pt/DPC) exhibited significantly improved ORR performance in the half and single cells, compared with the conventional carbon-supported Pt catalyst. The superior ORR stability of Pt/DPC may be as a result of the particular interaction between Pt catalyst and DPC support as a doped carbon. Graphical | - |
