<P>PROBLEM TO BE SOLVED: To effectively carry out scavenging in respective single cells in a fuel cell stack. <P>SOLUTION: The fuel cell stack is provided with a columnar through-hole which is penetrated in the laminating direction of a stack structure, and which forms a manifold to be branched and to supply gas to the respective single cells 40, a cylindrical member 200 which has nearly the same diameter as that of the through-hole and which has been inserted rotatably into the through-hole over the whole length direction of the through-hole, and a rotation driving mechanism in order to rotate the cylindrical member. The cylindrical member 200 is provided with a dry gas supply port 220 in order to supply the dry gas supplied interior the cylindrical member 200 from a branched flow passage 46p to respective single cells 40, and in the cylindrical member 200, the dry gas supply port 220 is formed so that the single cells 40 to which the dry gas will be supplied will be changed according to rotation of the cylindrical member 200. <P>COPYRIGHT: (C)2008,JPO&INPIT |
