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.
