Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To satisfactorily discharge condensate water from a fuel cell stack while keeping manufacture cost of the fuel cell stack low and keeping productivity high.SOLUTION: A fuel cell stack 1 includes: a laminate 2 including a plurality of fuel battery unit cells 3c which are laminated mutually in a lamination direction LS; end plates 6a and 6b; a pressure plate 7; and a compression member. Within the laminate, a hydrogen gas outflow passage 10ho is provided which crosses one end face 2a of the laminate, penetrates the laminate and extends in the lamination direction, and a hydrogen gas flow passage 3ch of the fuel battery unit cell is communicated to the hydrogen gas outflow passage. The fuel cell stack 1 further includes: a through-hole 12 which penetrates the second end plate and the pressure plate, further crosses another end face 2b of the laminate, penetrates the laminate and achieves the hydrogen gas outflow passage; and a nested conduit tube 13 which is disposed within the through-hole and mutually communicates the hydrogen gas outflow passage and the outside of the fuel cell stack.SELECTED DRAWING: Figure 1
