PROBLEM TO BE SOLVED: To uniform the degree of cooling in the vertical direction at a fuel cell stack.SOLUTION: In a fuel cell stack, an anode side separator 50 is mounted between a plurality of membrane electrode assemblies. The anode side separator 50 includes a separator central area 50A opposed to a power generation area of each of the membrane electrode assemblies; a plate-like outer edge part 50B extending from the separator central area 50A to the outer edge; and a plurality of cooling medium supply manifolds 82a to 82c provided in the outer edge part 50B, and aligned in the vertical direction when the fuel cell stack is placed. Further, in each beam part dividing the adjacent cooling medium supply manifolds 82a to 82c from each other is provided a reinforcement rib 95. The reinforcement rib 95 includes a connection rib 96 extending to an area between each of the cooling medium supply manifolds 82a to 82c and the separator central area 50A, and a flow distribution rib 94. |
