PROBLEM TO BE SOLVED: To increase a three-phase interface formation part for improving a function as an electrode for a fuel cell. SOLUTION: This electrode 20 is constructed of carbon particles 22 carrying platinum particles 24 serving as a catalyst and electrolyte particles 26 having a grain size smaller than that of the carbon particles 22. Over the whole of the electrode, minute clearances are formed and a uniform three-phase interface is formed in the electrode as a whole, and consequently, performance as the electrode can be improved. When this electrode 20 is used, performance of the fuel cell is improved. |
