Abstract
In a fuel cell stack, knock pins extending in a stacking direction are provided between a first end plate and a second end plate for positioning a stack body. The first end plate and the second end plate have insertion holes for insertion of knock pins. A diameter-increasing surface is formed in an inner circumferential surface of each insertion hole in a direction spaced from the knock pin to increase the diameter of the insertion hole.
