ABSTRACT:
A fuel cell stack includes unit cells. At one side of the unit cells, an oxygen-containing gas supply passage and a fuel gas discharge passage having different opening areas are provided. At the one side of the unit cells, a recess is provided near the fuel gas discharge passage having a relatively small opening area. A cell voltage terminal is provided in the recess such that the cell voltage terminal does not protrude outwardly from the side of the unit cells.
