PROBLEM TO BE SOLVED: To settle an ion conductive component while keeping it in a desired water containing rate by coating an electronically conductive catalyst supporter with electrode paste, followed by removing an organic solvent and settling of the ion conductive component while forcibly moistening the supporter and the paste. SOLUTION: Carbon paper 16, which is previously subjected to a water repellent treatment, is coated with electrode paste. With water 26 reserved inside a reservoir 28, the paper 16 is held by a cover 36 via suspending means 30 with the surface coated with the electrode paste facing upward. Subsequently, when a first heater 24 is driven by a first temperature regulator 22, the water 26 is boiled to forcibly moisten the paper 16 and the electrode paste. At this time, a second temperature regulator 32 is driven, thereby increasing an ambient temperature sequentially or stepwise. Consequently, an organic solvent contained in the electrode paste is removed and an ion conductive component is settled while the content of water contained in the ion conductive component is effectively kept. After a degreasing treatment, an anion exchanging membrane is integrated with the paper 16 after steam drying. |
