Abstract
An end plate includes a plate body, fastening portions, and ribs. The plate body is rectangular and includes two long sides and two short sides. The plate body is arranged on an end of a cell stack of a fuel cell. The fastening portions are fastened to a case containing the cell stack. The fastening portions extend along edges of the plate body. The ribs are arranged in a grid-like manner on the plate body surrounded by the fastening portions. The ribs are arranged so that recesses defined between the ribs each have a quadrilateral shape in which two diagonals have different lengths. The ribs are arranged so that the recesses extend in a direction in which the ribs extend and so that a longer one of the two diagonals of each of the recesses extends parallel to the short sides of the plate body.
