ABSTRACT:
The present invention makes it possible to remove an organic solvent in an electrode paste and fix an ion-conductive component while maintaining a desired moisture content. Specifically, a sheet of carbon paper applied with the electrode paste is horizontally held in a tank which comprises a drying apparatus. Water in the tank is brought to the boil by the aid of a first heater. Accordingly, the organic solvent in the electrode paste is removed, and the ion-conductive component is fixed, while forcedly humidifying the carbon paper and the electrode paste with steam.
