PROBLEM TO BE SOLVED: To provide a lightweight and low-cost fuel cell stack that effectively reduces the number of seal members that are provided integrally with metal separators.SOLUTION: A fuel cell stack 10 includes anode metal separators 34 and cathode metal separators 40. A metal outer edge 34me of each anode metal separator 34 and a metal outer edge 40me of each cathode metal separator 40 are exposed externally through a first seal member 90 and a third seal member 94, respectively. A metal outer edge 38me of each intermediate metal separator 38 is covered with a second seal member 92. The second seal member 92 has plate-like covering sections 92e1 and 92e2 that extend to such positions as to cover outer edges of an adjacent anode metal separator 34 and an adjacent cathode metal separator 40. |
