Abstract
A solid state electrolyte fuel cell stack includes: layered solid state electrolyte fuel cells, each formed by a solid state electrolyte body having a fuel pole in contact with a fuel gas and an air pole in contact with an oxidant gas; and inter-connectors arranged between the solid state electrolyte fuel cells so as to separate a gas flow path between the solid state electrolyte fuel cells and assure electric conduction between the solid state electrolyte fuel cells. The solid state electrolyte fuel cell stack has two or more air vents for supplying a fuel gas or two or more air vents for supplying the oxidant gas which vents penetrate a part or the whole of the fuel cell stack in the stack layering direction. The different air vents communicate with the different solid state electrolyte fuel cells.
