<P>PROBLEM TO BE SOLVED: To obtain a heat self supporting solid oxide fuel cell system in which heat self supporting can be achieved even at the time of partial load operation. <P>SOLUTION: As for the heat self supporting solid oxide fuel cell system, a solid oxide fuel cell stack and an off-gas combustion part and, in addition, a heat storage material layer are arranged in a heat-insulated vessel, and in the heat storage material layer, an air inlet tube and an air outlet tube are arranged, and at the same time a by-pass flow path is installed against that flow path, and in the full load operation, surplus heat is stored in the heat storage material layer and at the same time the air is supplied into the stack by letting the air bypass into a bypass flow path, and in the partial load operation, the air is returned into the stack by letting the air pass through the heat storage material, and the heat stored in the full load operation is recovered and returned to the stack. <P>COPYRIGHT: (C)2004,JPO |
