PROBLEM TO BE SOLVED: To eliminate the need for a dummy cell and make it possible to secure an optimum cooling condition with a compact and economical configuration.SOLUTION: A fuel cell stack 10 includes a power generation unit 12. At one end of the power generation unit 12 in a stacking direction, a first end part power generation unit 12a formed by stacking a third metal separator 20, a second electrolyte membrane electrode structure 16b, and a second metal separator 18 toward the outside is disposed. At the other end of the power generation unit 12 in the stacking direction, a second end part power generation unit 12b formed by stacking a first metal separator 14, a first electrolyte membrane electrode structure 16a, and a second metal separator 18 toward the outside is disposed. |
