<P>PROBLEM TO BE SOLVED: To provide a solid oxide fuel cell decreasing fuel flowing through a gap passage without coming in contact with a fuel cell stack and enhancing utilization efficiency by suppressing the formation of a gap passage between a metal wall and an insulating part caused by the difference between coefficients of linear expansion, and enhancing power generation efficiency by keeping contact resistance between a current collecting part and a fuel cell cell low. <P>SOLUTION: In the solid oxide fuel cell having a fuel cell stack formed by electrically connecting a plurality of fuel cell cells, an insulating part arranged outside the fuel cell stack, and the metal wall arranged outside the insulating part, a gap passage cross section decreasing means decreasing the cross section of the gap passage between the insulating part and the metal wall is installed. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
