| Outline of Final Research Achievements |
The aim of this study is to obtain a concept to design high performance platinum-free electrode catalysts for alkaline anion exchange membrane fuel cell having higher catalytic activity than platinum-based catalysts. The following materials and structure-activity relationship were examined: (1) Activity dependence of Ni oxides on oxidation number, (2) Effect of promoters to CoO, (3) Size effect of nano-sized Ag metal particles, (4) Ru-Ir nano-bimetal particles. We found that (4) an alloyed Ru-Ir bimetal nano-metal catalyst is very effective for hydrogen oxidation reaction. The obtained Ru-Ir/C nano-bimetal catalyst showed twice higher hydrogen oxidation activity than Pt/C.
