<P>PROBLEM TO BE SOLVED: To regulate movement of a separator in a plane direction occurring by thermal strain under a high-temperature atmosphere at power generation, and prevent damage to power generating cells. <P>SOLUTION: In the fuel cell stack 1 of a flat lamination type made by alternately laminating power generating cells 5 and separators 8 and weighing the laminated body from a lamination direction, each separator 8 is provided with a plurality of through-holes 22 penetrating in the lamination direction, into which 22, fixing rods 23 are inserted for regulating movement of the separator 8 in a plane direction due to thermal strain at operation. <P>COPYRIGHT: (C)2007,JPO&INPIT |
