<P>PROBLEM TO BE SOLVED: To prevent cracks in a cell while making it compact and raising power generation efficiency by obtaining high power generation output. <P>SOLUTION: Through a porous metal plate 6, which is inserted to each six recesses 8 arranged in the shape of a ring at the front and back surfaces of separators 7, each the single cells 5 are arranged by pressing, respectively, and the single cells 5 of six sheets are connected electrically in parallel. These separators 7 and the single cells 5 are laminated by turn, and a stack 4 is constituted. A fuel gas preheating pipe 17 and an oxidizer gas preheating pipe 16, which heat fuel gas and oxidizer gas beforehand, are arranged in the central penetration holes 7a of the separators 7, respectively. Each the gas beforehand heated even to the reaction temperature are supplied to recessed grooves 9 in each of the recesses 8 of each of the separators 7. The stack 4 is enclosed by the heat insulating material layer 20 and further, it is enclosed by a seal component 2 through the space 26 of its outside. The gas for heating is supplied inside of the heat insulating material layer 20 by the heating gas supplying component 25 and the gas for cooling is supplied to inside of the space 26 by cooling gas supplying component 27. <P>COPYRIGHT: (C)2003,JPO |
