<P>PROBLEM TO BE SOLVED: To provide a solid oxide fuel cell from which an elevated temperature exhaust gas is also obtained with a low temperature exhaust gas, after a heat recycling has been performed. <P>SOLUTION: The solid oxide fuel cell contains fuel cell stacks 1, constituted by stacking many power generation cells 5 in a heat insulation housing 30, supplies a reaction gas to the interior of the fuel cell stacks 1 at the operation time and produces a power generation reaction. At the same time, the solid oxide fuel cell exhausts the exhaust gas produced at the power generation reaction to the outside. Each solid oxide fuel cell independently is equipped with an exhaust gas discharge mechanism 30a, for exhausting the part of the exhaust gas from the fuel cell stacks 1 directly to the exterior, and an exhaust gas discharge mechanism 20a, for heat recycling the part of the exhaust gas to the fuel cell stacks 1, respectively. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
