PROBLEM TO BE SOLVED: To provide a fuel cell stack which can effectively reduce the number of processes in resin molding to a separator so as to improve the efficiency and cut down the cost of manufacturing process of the separator.SOLUTION: A power generation unit 12 of a fuel cell stack 10 includes: a first separator 30; a first electrolyte membrane-electrode structure 32a; a second separator 34; a second electrolyte membrane-electrode structure 32b: and a third separator 36. A plurality of resin guide parts 82 are provided on the periphery of the second separator 34. Each of the resin guide parts 82 has: a first swollen part 82b and a second swollen part 82c extending in a stacking direction to positions covering the peripheries of the adjacent first separator 30 and the adjacent third separator 36, respectively. |
