A solid oxide fuel cell in which one or more cell units of the fuel cell are disposed within or in proximity to a flame, produced upon combustion of a fuel material, and are exposed to the flame, thereby generating electricity. In the solid-oxide fuel cell, the fuel cell is provided with a combustion chamber for combusting the fuel material, the combustion chamber has a configuration of a cylinder, and a wall of the cylindrical combustion chamber is defined by the cell units of the fuel cell, and the cell units comprise a substrate consisting of a solid electrolyte, an anode layer formed on a combustion chamber side of the substrate and a cathode layer formed on another side of the substrate opposed to the anode layer. The combustion chamber is especially suitable for the combustion of solid fuels. |
