PROBLEM TO BE SOLVED: To provide a fuel cell stack capable of attaining reduction in weight and attaining reduction in cost of manufacture while maintaining a strength and rigidity substantially equal to an end plate which is formed from a high-strength and high-rigidity metal mass.SOLUTION: A fuel cell stack 1 is formed by disposing end plates 10 in both ends of a cell laminate 3 which is formed by laminating a plurality of fuel cells 2. The end plate 10 includes: a metal thin plate 31; and a deformed cross-sectional metal plate 41 in which a plurality of polygonal hollow parts 43 formed in a penetrating manner along a direction of lamination of the fuel cells 2 are disposed while being spaced apart from each other. A plurality of metal thin plates 31 and deformed cross-sectional metal plates 41 are laminated alternately. |
