<P>PROBLEM TO BE SOLVED: To provide a fuel cell stack capable of changing distribution ratio of fluid to be distributed to each cell while suppressing increase of the types of components. <P>SOLUTION: A manifold 55 which distributes at last one fluid out of a fuel gas, an oxidation gas, and coolant to each cell 50 is installed along lamination direction in a cell laminate 51 in which a plurality of cells 50 to generate power by electrochemical reaction of the fuel gas and the oxidation gas are laminated. Projections 61, 64 which protrude in the manifold 55 are provided at current collectors 52, 53 of the fuel cell stack 10 having the current collectors 52, 53 to take out power generated by the cells 50 on both sides in lamination direction, and the distribution ratio of the fluid to be distributed to each cell 50 by the manifold 55 is changed by these projections 61, 64. <P>COPYRIGHT: (C)2008,JPO&INPIT |
