To provide a solid oxide fuel cell in which power generation efficiency is improved by minimizing a temperature distribution in a cell longitudinal direction and between each of cells, and which is suitable for recovering unused excess fuel gas.
The solid oxide fuel cell is provided with a plurality of cells in which an exhaust gas recovering chamber and an exhaust gas combustion chamber are formed in order from the side of a cell reaction chamber, and longitudinal directions of cylindrical bag shaped cells are almost horizontal so as to form a layer, a layer partition member for dividing layers of the laminated cells, a first sealing member for dividing the cell reaction chamber and the exhaust gas recovering chamber, a second sealing member for dividing the exhaust gas recovering chamber and the exhaust gas combustion chamber, a third sealing member to divide the cell reaction chamber and a fuel gas supply chamber, and a cell supporting member for holding the cylindrical cells in the cell reaction chamber. The partition member has a fuel gas passage connected through the fuel gas supply chamber and an exhaust gas passage connected through the exhaust gas recovering chamber.
