<P>PROBLEM TO BE SOLVED: To provide technology capable of suppressing stagnation of impurities in an internal reaction gas passage of a fuel cell stack. <P>SOLUTION: The fuel cell stack has a plurality of stacked cells. A target cell is equipped with an electrolyte layer, first and second electrode layers interposing the electrolyte layer between them, and first and second separating layers installed on the outside of each of the first and second electrode layers and separating the target cell from another cell adjacent to the target cell. A first internal reaction gas passage 212 for supplying a first reaction gas, given from the outside to the first electrode layer, is installed between the first electrode layer and the first separating layer. The target cell has a moving body 160 for stirring the first reaction gas in the first internal reaction gas passage. The moving body moves caused by vibration applied to the fuel cell stack. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
