| Outline of Final Research Achievements |
Polymer electrolyte fuel cells (PEFCs) are applied to the fuel cell vehicles, and residential power generation. Platinum-based catalysts supported on carbon are typical cathode catalysts for PEFCs, but the degradation of the carbon support in the high potential region is a problem to be solved to apply for the fuel cell vehicles. We invented the new tin oxide nanoparticle supports with "fused-aggregated network structure" as candidate supports for high durable cathode catalysts by the flame combustion method. We also controlled the Pt/support (solid /solid) interface and Pt/gas (solid/gas) interface by sintering procedure, and evaluated the electronic conductivity, electrochemical properties and durability of Pt or Pt alloy catalyst. We found that the Pt alloy catalysts supported on the oxide nanoparticle support showed the 2.5 times higher oxygen reduction reaction activity and several hundred times durability compared with commercial Pt catalyst supported on the carbon catalyst.
