Abstract: A manufacturing method includes providing a cell stack including fuel cells and has a first end and a second end. A first end plate is provided at the first end of the cell stack. The first end plate has a first end plate through hole. A second end plate is provided at the second end of the cell stack. A connecting member is provided to connect the first end plate and the second end plate. A first knock is inserted into the first end plate through hole and into a first connecting member installing hole. A first seal is located between the first knock and the first end plate in the first end plate through hole. The first end plate is moved in the stacking direction to contact the connecting member. A fastening member is inserted into the first knock.

Abstract: A fuel cell stack includes unit cells, a resin load receiver, and a connecting member. The resin load receiver is provided in each of a first and second separators. The resin load receiver has a projecting portion that projects outwardly from an outer peripheral edge of each of the first and second separators and that has a projecting portion lateral face. The connecting member includes an engagement portion engaged with the resin load receiver and having a depressed portion into which the projecting portion is inserted and which has a depressed portion lateral face facing the projecting portion lateral face. A distance between the projecting portion lateral face and the depressed portion lateral face at a root portion of the projecting portion is smaller than a distance between the projecting portion lateral face and the depressed portion lateral face at an end of the projecting portion.
