PROBLEM TO BE SOLVED: To provide a fuel cell having a structure in which the length of the whole structure in the direction of the stack has been made shorter by eliminating the separator and the structure of passages has been made simple, and also series or parallel connection between each generating element can be made freely. SOLUTION: Generating elements 2 of three layer structure made of a negative electrode 4, a positive electrode, and a conductor membrane 3 provided in close contact between the negative electrode and the positive electrode are arranged plural pieces in the direction of the layer. In this arrangement, the opposing electrodes between the adjoining generating elements are made to be the same pole, and the only hydrogen gas supply passage is provided between the opposing negative electrodes, and the only air supply passage is provided between the opposing positive electrodes, and hydrogen is supplied to the negative electrodes and air is supplied to the positive electrodes. The opposing electrodes between the adjoining generating elements are connected by an insulator 8 and the hydrogen gas supply passage and the air supply passage are sealed. |
