A phosphoric acid fuel cell is efficiently produced. As a matrix, a material is used which can hold therein a impregnating liquid electrolyte and which can release the impregnating liquid electrolyte when the material is pressed. In step S1, the matrix is impregnated with the liquid electrolyte such as phosphoric acid, sulfuric acid, and methanesulfonic acid to provide an electrolyte layer (18). In step S2, the electrolyte layer (18) is interposed between an anode electrode (14) and a cathode electrode (16) to provide a stack. In step S3, the stack is pressed. By pressing the stack, the electrolyte layer (18) is joined to the anode electrode (14) and the cathode electrode (16) and the liquid electrolyte is diffused from the matrix to electrode catalyst layers (12, 12) of both of the electrodes (14, 16). <IMAGE> |
