<P>PROBLEM TO BE SOLVED: To provide a fuel cell stack having a simple and economic structure, capable of maintaining an intended power generation property. <P>SOLUTION: On the fuel cell stack 10, an end part separator 18a, a terminal plate 20a, an insulation plate 22a, and an end plate 24a are arranged at one end side of a lamination body 14 in lamination direction. A concave part 30a for housing the terminal plate 20 is formed on the insulation plate 22a, and a bypass flow passage 80 for draining condensed water, communicating a fuel gas inlet communication hole 54a with a fuel gas outlet communication hole 54b, is formed at outside of the concave part 30a. An insulation seal member 88 covering the bypass flow passage 80 is formed on the end part separator 18a, and an insulated flow passage is constituted together with the bypass flow passage 80. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
