PROBLEM TO BE SOLVED: To provide a phosphoric acid introducing method for introducing phosphoric acid into an electrode used in a fuel cell main body at high speed. SOLUTION: A phosphoric acid layer 3 is formed on the upper surface of an electrode 1 placed on a porous body 4. A soft sheet 7b is arranged on the phosphoric layer 3, and the lower surface of the electrode 1 is sucked in vacuum with a suction pump through an exhaust pipe 6 and a fluid path 5b to introduce phosphoric acid into the electrode 1, then the soft sheet is removed. A mixed solution layer of phosphoric acid and alcohol is formed instead of the phosphoric acid layer 3, and alcohol may be removed before or after suction. The electrode into which phosphoric acid is introduced is hung and held in non-contact state and carried. |
