| Research Abstract |
In this study, the oxide-supported precious metal electrocatalysts and the carbide-based electrocatalysts were fabricated for intermediate-temperature fuel cells operating in the temperature range of 150-300℃. For the oxide-supported electrocatalysts with a small loading of precious metals, the electrochemical activity for the hydrogen oxidation or oxygen reduction was comparable to that of conventional platinum/carbon electrocatalysts. This result suggested the feasibility of new electrocatalyst with a small amount of precious metals. However, it was also clarified that it is essential to develop the fabrication procedure of electrocatalysts with high dispersion of active sites over oxide supports with a relatively low surface area.
