<P>PROBLEM TO BE SOLVED: To squeeze down the supply of fuel gas to a damaged power for generating cell and for electrically short-circuit a stack, including the damaged cell, at a higher temperature. <P>SOLUTION: A solid oxide fuel cell stack of an inside manifold type laminates a plurality of single stacks constituted of separators 2a, 2b equipped with gas flow channels 7 and power generating cells, and constitutes a manifold of fuel gas, by coupling of through-holes 3 formed in each separator 2a, 2b. The solid oxide fuel cell stack is provided inside the manifold with a spiral-shaped repair member 10, capable of turning with an axis along a lamination direction of the single stacks as a center, and the repair member 10 is arranged at a position of the gas flow channel 7, connecting the manifold and the power generating cells. <P>COPYRIGHT: (C)2009,JPO&INPIT |
