Abstract:
A fuel cell stack includes a casing which is formed by a combination of a plurality of plates; and a seal member interposed between the plurality of plates. The plurality of plates includes a pair of first plates facing each other in a first direction with the cell stacked body interposed therebetween, a pair of second plates facing each other in a second direction with the cell stacked body interposed therebetween, and a pair of third plates facing each other in a third direction with the cell stacked body interposed therebetween. The seal member has a frame seal which is formed in a frame shape extending to follow an outer circumferential portion of the first plate, an extension seal which extends in the first direction integrally with the frame seal, and a connection seal which is close to or in contact with the extension seals facing each other.

Claim (Index 1):
A fuel cell stack comprising:\n a cell stacked body in which a plurality of fuel cells are stacked; a casing which is formed by a combination of a plurality of plates and houses the cell stacked body; and a seal member interposed between the plurality of plates, wherein the plurality of plates includes:\n a pair of first plates facing each other in a first direction with the cell stacked body interposed therebetween, \n a pair of second plates facing each other in a second direction orthogonal to the first direction with the cell stacked body interposed therebetween, and \n a pair of third plates facing each other in a third direction orthogonal to the first direction and the second direction with the cell stacked body interposed therebetween, and \n wherein the seal member has:\n a frame seal portion which is formed in a frame shape extending to follow an outer circumferential portion of the first plate, and is sandwiched between the first plate and the second plate and between the first plate and the third plate in the first direction, \n an extension seal portion which extends in the first direction integrally with the frame seal portion, and is sandwiched between the second plate and the third plate; and \n a connection seal portion which extends between the second plate and \n the third plate in the first direction, and is close to or in contact with the extension seal portions facing each other in the first direction.
