PROBLEM TO BE SOLVED: To provide a fuel battery stack that can reduce the voltage loss at the projection portion of a collector plate and enhance the performance of the fuel battery stack.SOLUTION: In a fuel battery stack 1, a midpoint M in the width W of a second projection portion 15 exists within a belt-like range (that is, connectable range SKH) between a first contact line L1 contacting the outer periphery of one through-hole 10c of a collector plate 9 and a second contact line L2 contacting the outer periphery of the other through-hole 10d. Thus, the flow of power (current) generated in the fuel battery stack 1 is difficult to be hindered by the through-hole 10, so that power can be easily supplied from the collector portion 65 of the collector plate 9 via the second projection portion 15 to the second output terminal 16. Therefore, the voltage loss is reduced, and the performance of the fuel battery stack 1 can be enhanced.SELECTED DRAWING: Figure 7 |
