Abstract:
A fuel cell stack includes a plurality of single cells stacked and a manifold. The plurality of single cells each include a first separator including a seal portion surrounding the manifold and including a hollow protrusion and a fluid passage portion allowing the fluid to flow between the manifold and a space on the opposite side of the seal portion from the manifold via the hollow of the seal portion, a second separator disposed on the side opposite to the side on which the seal portion projects, of the first separator, and an electric insulating frame disposed on the opposite side of the second separator from the first separator. The second separator includes a flat-and-bulge portion in a surface facing the seal portion, along an abutment region of the seal portion and the electric insulating frame.

Claim (Index 1):
A fuel cell stack comprising a plurality of single cells stacked, and a manifold that is provided so as to extend through the plurality of single cells and allows a fluid to flow therein, wherein:\n each single cell of the plurality of single cells includes a first separator including a protrusion including (i) a seal portion that surrounds a periphery of the manifold and (ii) a fluid passage portion, a first member disposed on a side of the first separator such that (i) a first space is arranged between the protrusion and the first member and (ii) the fluid passage portion allows the fluid to flow between the manifold and a second space on an opposite side of the seal portion from the manifold via the first space, the side being opposite to a side on which the seal portion projects, and a second member that is provided on an opposite side of the first member from the first separator and includes a first elastic member; the seal portion of a first single cell from among the plurality of single cells is in abutment with the second member of a second single cell adjacent to the first single cell; the first member of the first single cell includes a flat-and-bulge portion in a surface of the first member, the surface facing the seal portion, the flat-and-bulge portion extending along a region where the seal portion and the second member of the second single cell abut against each other.
