<P>PROBLEM TO BE SOLVED: To provide a fuel cell stack in which drainage of water in a fuel cell is ensured without complicating the structure of the fuel cell, while reducing the size and the cost of the fuel cell. <P>SOLUTION: In a non-power generation member 14 provided at the end of a cell laminate 12, a through hole 29 having an inside opening on the cell laminate 12 side and an outside opening on the reverse side of the cell laminate 12 side is formed. A seal member 30 which forms a space 32a in the through hole 29 by closing the outside opening and opening the inside opening is disposed in the through hole 29. The space 32a is formed from a manifold 16 for discharging reaction gas to a manifold 18 for drainage when viewed from the cell lamination direction, and the manifold 16 for discharging reaction gas and the manifold 18 for drainage are interconnected by a communication passage 20. <P>COPYRIGHT: (C)2013,JPO&INPIT |
