Abstract:
An end plate of a fuel cell stack includes a metal plate body including a plurality of through holes and a resin cover that covers a wall surface defining each of the through holes. The cover includes a body, a flange projecting outward in a radial direction from an outer end of the body, an annular rim extending toward the inner side from an outer edge of the flange, and a coupling rib that couples an inner circumferential surface of the rim to an outer circumferential surface of the body. The plate body further includes an outer end surface including a recess. The recess is filled with the flange, the rim, and the coupling rib.

Claim (Index 1):
An end plate of a fuel cell stack arranged on an end of a cell stack body of the fuel cell stack in a stacking direction and including a plurality of circulation holes through which a fluid flows to and from flow passages in the cell stack body, the end plate comprising:\n a metal plate body including a plurality of through holes that form the circulation holes; and a resin cover that covers a wall surface defining each of the through holes, wherein when referring to a side of the plate body in a thickness-wise direction that is closer to the cell stack body as an inner side and a side of the plate body that is farther from the cell stack body as an outer side, the cover includes\n a body that covers the wall surface of the corresponding through hole, \n a flange projecting outward in a radial direction from an outer end of the body, \n an annular rim extending from an outer edge of the flange toward the inner side, and \n a coupling rib that couples an inner circumferential surface of the rim to an outer circumferential surface of the body, and \n the plate body further includes an outer end surface including a recess, wherein the recess is filled with the flange, the rim, and the coupling rib.
