PROBLEM TO BE SOLVED: To provide a fuel battery stack that can reduce the voltage loss and enhance the performance of the fuel battery stack in a power takeout structure for the fuel battery stack.SOLUTION: A fuel battery stack comprising plural laminated unit batteries, includes: plural through-holes which are provided at the outer edge frame portions of the respective unit batteries and penetrate through the laminated stack in the lamination direction; a collector plate which is provided to the end portion of the stack and has through-holes 10c, 10d provided at the same positions as the through-holes; a projecting portion 67 of the collector plate to which a terminal for taking out power is connected; and a connection area SR where the projection portion 67 and a second output terminal 15 for taking out power are electrically connected to each other. The connection area SR is formed within a connectable range SKH which is a belt-like range between a first contact line L1 contacting the outer periphery of one through-hole 10c of the stack and a second contact line L2 contacting the outer periphery of the other through-hole 10d.SELECTED DRAWING: Figure 8 |
