To provide an electrode catalyst for fuel cells, which is obtained efficiently by a simple process, without using a silica template, unlike in the conventional process, which is relatively large in mesopore diameter (5 nm or more), which enables catalyst particles deposited stably in the mesopores, and which can readily develop a highly triple-phase interface state. Such an electrode catalyst for a fuel cell is constituted with: a mesoporous carbon support obtained by heating and baking for carbonization a mixture of a surfactant and carbon precursors; and catalyst particles carried by the support. Further, it is possible to obtain a fuel cell, which has: a fuel electrode; an air electrode; and an electrolyte membrane interposed between the electrodes, in which at least one of the fuel electrode and the air electrode contains the electrode catalyst. |
