PURPOSE:To obtain the subject fuel cell easily and in a short time by making this in a simple shape that an oxygen electrode, a solid electrolyte, and a fuel electrode are respectively laminated in order in cylindrical shape. CONSTITUTION:For a simple battery 10, oxidizing gas such as air is supplied continuously from a gas supply pipe 14 into inside, and fuel gas such as hydrogen gas, etc., is used for the atmosphere at the periphery, whereby electrochemical oxidizing and reducing reactions occur through a solid electrolyte 12 resulting from the difference of oxygen concentration between both the inside and outside of the solid electrolyte 12. As a result, electromotive force occurs such as that an oxygen electrode 11 becomes an anode and a fuel electrode 13 becomes a cathode. It follows that the electrodes 11 and 13 are formed, respectively, on both sides of the inside and outside of the solid electrolyte 12 this way, and that the electrode 13 at the outermost layer is exposed to the outside as it is, but the electrode 11 on the inner periphery side is lead out to the outside through the gas supply pipe 14 leading to this. Hereby, if each element such as the solid electrolyte 12, etc., is formed in order to the outer periphery of the element on the inner periphery side, that will do, and unefficient work such as masking, etc., can be obviated, and work efficiency in manufacturing can be improved. |
