Abstract: PROBLEM TO BE SOLVED: To manufacture a jointed body of an electrolyte film and an electrode having a sufficient gas permeability and conductivity. SOLUTION: Heat is applied to zinc powder to burn a three-dimensional structure, which is pulverized to form a three-dimensional pore forming material (S100). This material is dispersed in a solvent along with carbon fine particles carrying catalyst to make paste ink (S110), and to form a sheet electrode forming member (S120). Furthermore, the formed electrode forming member is dried (S130), and the dried electrode forming member is pressed to both sides of an electrolyte film by means of hot pressing (S140). A jointed body obtained in this way is boiled with dilute sulfuric acid to effect elution of the pore forming material (S150), and a power generation layer is finished as the jointed body of an electrode and the electrolyte film.  Since three-dimensional communicating fine pores are formed in the electrode of the power generation layer by the action of the three-dimensionally structure pore forming material, the electrode exhibits sufficient gas permeability and conductivity.
