PROBLEM TO BE SOLVED: To restrain displacement of a single cell in a plane direction while preventing breakage or deformation of the single cell.SOLUTION: A single cell 50 of a fuel battery stack 10 has a pair of separators 60, 61 sandwiching a power generation part 63 from both sides. A convex-like part 110 contacting the separator 61 of the other single cell 50 is formed on an outer periphery of the power generation part 63 in the separator 60. Also, a concave-like part 120 is formed on the outer periphery of the power generation part 63 in the separator 60 of the single cell 50, and a gasket 130 projecting inside the concave-like part 120 in the separator 60 of the other single cell 50 and contacting the concave-like part 120 is provided on the outer periphery of the power generation part 63 in the separator 61. |
