<P>PROBLEM TO BE SOLVED: To provide a fuel cell stack which can improve power generation efficiency by making uniform a temperature distribution in an arrangement direction of the fuel cells, in the fuel cell stack made by arranging a plurality of fuel cells. <P>SOLUTION: The fuel cell stack 1 is composed of a plurality of fuel cells 2 composed of by lamination of a fuel cell side electrode layer 5, a solid electrolyte layer 6 and an air side electrode layer 4 in this order and is arranged to be electrically connected in series on a supporting base plate 8. A distance between the plurality of the fuel cells arranged in a central part in the arrangement direction of the fuel cells 2 is set up wider than a distance between the plurality of the fuel cells 2 arranged in edge sides in the arrangement direction of the fuel cells, and as a result, a temperature distribution of the fuel cell stack 1 can be made more uniform. <P>COPYRIGHT: (C)2008,JPO&INPIT |
