PROBLEM TO BE SOLVED: To suppress the corrosion of a metal plate in a collector plate arranged by laminating different kinds of metal plates.SOLUTION: A collector plate for a fuel battery comprises: a conductive first metal plate having a terminal part; and second and third metal plates, which are higher than the first metal plate in corrosion resistance, and hold the first metal plate therebetween. The collector plate has: a first through-hole serving to lead a fluid, which is present at least between the first and second metal plates or between the first and third metal plates, to outside the collector plate, and extending through the first to third metal plates; and a first seal material for sealing an end face of the outer periphery of the collector plate. In the collector plate, a wall face of the first through-hole is not sealed.SELECTED DRAWING: Figure 2 |
