| Research Abstract |
Improvements of the mass activity for Oxygen Reduction Reaction (ORR) and the durability on the platinum catalyst at the cathode in Polymer Electrolyte Fuell Cells (PEFCs) are one of the most important issues for its commercialization. However, the high activity and the high durability of the commercially available Pt/C catalyst are in the relation of the trade-off. Therefore, it is necessary to develop the technology that is able to solve the conflicting problem. Pt dissolution is one of the serious problems for the high durability of the catalysts in the PEFC. In the present study, the Au sub-monolayer modified on Pt by under potential deposition (UPD) technique for stabilized surface Pt atoms, and the change in the frequency and electrochemical surface area were investigated.
