<P>PROBLEM TO BE SOLVED: To enable thinning cooling with a simple and economical structure. <P>SOLUTION: The fuel cell stack 10 is structured of a plurality of power generation units 12 laminated along a horizontal direction. A first fuel gas flow channel 36 of a first metal separator 14, a first oxidant gas flow channel 50 of a second metal separator 18 and a second fuel gas flow channel 58 of the second metal separator 18, structuring each power generation unit 12, are set in the same phase with each other along a lamination direction. On the other hand, a second oxidant gas flow channel 66 of a third metal separator 20 structuring each power generation unit 12, is set in a different phase from the first fuel gas flow channel 36, the first oxidant gas flow channel 50 and the second fuel gas flow channel 58. <P>COPYRIGHT: (C)2010,JPO&INPIT |
