<P>PROBLEM TO BE SOLVED: To provide a fuel cell stack structure capable of shortening a starting time and achieving compactness while improving the utilization efficiency of a reforming temperature and the uniformity of the whole temperature distribution. <P>SOLUTION: The fuel cell stack structure is constituted by laminating at a center a plurality of solid electrolyte fuel cell units 1 which have circular cell plates 2 that hold unit cells and have gas inlet holes 21 and gas exhaust holes 22 at the center, a circular separator plate 3 that has a gas inlet hole 31 and a gas exhaust hole 32 at the center and is jointed to the cell plate 2, and a center passage component 5 which is located between each center of both plates 2, 3 and carries out the supply and discharge of a fuel gas in the space through a gas inlet passage 51 communicating with the gas inlet holes 21, 31 and a gas exhaust passage 52 communicating with the gas exhaust holes 22, 32. The space between the adjoining solid electrolyte fuel cell units 1 is made to be an air passage and a porous body 20 is installed in the gas inlet passage 51A which is formed by the continuation of each gas inlet passage 51 of the center passage component 5. <P>COPYRIGHT: (C)2009,JPO&INPIT |
