Patent ID: 8273493

Claim:
A solid electrolyte fuel cell stack comprising: solid electrolyte fuel cells stack-layered therein, each of the solid electrolyte fuel cells including a cell body and a frame portion that encloses the cell body in a planar direction of the cell body, the cell body comprising a solid electrolyte having a fuel electrode, which contacts with fuel gas, and an air electrode, which contacts with oxidant gas; and interconnectors disposed between the respective solid electrolyte fuel cells to separate a gas flow between the solid electrolyte fuel cells and secure electric conduction between the solid electrolyte fuel cells, wherein vents for supplying the fuel gas are provided in the frame portions of the solid electrolyte fuel cells in such a manner that the vents for supplying the fuel gas penetrate a part or a whole of the solid electrolyte fuel cell stack in a stack-layering direction of the stack, wherein different vents for supplying the fuel gas communicate with the different solid electrolyte fuel cells, through holes forming respective different vents for supplying the fuel gas; wherein bolts are inserted through the through holes to press each of the solid electrolyte fuel cells which are stacked, in a stack-layering direction, so that the solid electrolyte fuel cells can be restrained in one body, and at least two of the vents for supplying the fuel gas pass through more than one of the interconnectors in the stack-layering direction but do not communicate with each cell body.
