PROBLEM TO BE SOLVED: To provide a fuel cell stack structure in which occurrence of cracks in a joining material is suppressed, the fuel cell stack structure including a plurality of flat plate-like cells joined to a support plate using the joining material to be arranged in a stacked manner.SOLUTION: In a fuel cell stack structure, one end part of each of a plurality of cells 100 is fixed on the top surface of a support plate 210 of a manifold using a joining material 300 such that each of the cells 100 protrudes from a surface of the support plate 210 along the longitudinal direction thereof, respectively, and the cells 100 are arranged in a stacked manner. For each of the cells 100, the ratio (Bave/L1) of "an average value Bave relating to the positions in the circumferential direction thereof of a side surface of the one end part of each of the cells 100 in a length (joint length B) of the longitudinal direction at a portion joined by the joining material 300 on the side surface" relative to "the total length L1 of the cells 100 in the longitudinal direction" is 0.01-0.2. |
