Abstract
An electrode base material is held by electrostatic attraction when a voltage from a DC power source is applied to electrodes for electrostatic attraction. A paste is applied to the electrode base material, and then the paste is dried to form the water-repellent layer. Subsequently, another paste is applied to the water-repellent layer, and then the paste is dried. Accordingly, the substantially flat electrode catalyst layer including an extremely small number of depressions is formed. The electrode of the fuel cell produced as described above can be used as an anode or a cathode.
