An electrode substrate (1) is dipped into an aqueous solution of a catalyst (3) in which carbon powder is suspended. The solution is circulated by a pump (5) through a tank (4). Electrodeposition is then carried out by employing the electrode substrate (1) as a cathode, so as to fix the carbon powder and the catalyst onto the electrode substrate. A catalyst electrode thus formed does not contain any binder such as polytetrafluoroethylene, so that it does not show any excessive voltage rise when in operation in a fuel cell. In addition, it is very easy to manufacture in comparison with catalytic electrodes manufactured according to prior art methods. |
