It is possible to suppress damage to a fuel cell as much as possible and to improve gas sealing performance and current collection performance. A fuel cell constituting a fuel cell stack includes a power generation reaction section, a peripheral edge that circulates around the power generation reaction section, a first reaction gas circulation section, and a second reaction gas circulation section. With. The first reaction gas circulation part 50 and the second reaction gas circulation part 52 are provided between the outside of the power generation reaction part 46 and the inside of the peripheral edge part 48. The fuel cell stack 10 includes a first load applying unit 64 that applies a first load to the peripheral portion 48 along the stacking direction, and a second load applying that applies a second load to the power generation reaction unit 46 along the stacking direction. Part 66. [Selection] Figure 2 |
