PROBLEM TO BE SOLVED: To provide a fuel battery stack that can suppress damage of a load reception portion as much as possible with a simple construction.SOLUTION: A unit cell 12 constituting a fuel battery stack 10 comprises first load reception parts 60a, 60b engaged with a first joint member 24, and second load reception parts 66a, 66b engaged with a second joint member 26. The first load reception part 60a has a convex portion 64a, and the first joint member 24 has a concave portion 76a in which the convex portion 64a is inserted. The interval between the side surface of the convex portion 64a and the side surface of the concave portion 76a is set to a smaller dimension at the base portion side of the convex portion 64a than that at the tip side of the convex portion 64a.SELECTED DRAWING: Figure 2 |
