<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a fuel cell stack, in which a variation of loads working on each of membrane electrode assemblies in a plurality of cell modules composing the fuel cell stack is controlled. <P>SOLUTION: The method of manufacturing a fuel cell stack includes: an ageing treatment step (steps S100, 110) of subjecting the cell module having the membrane electrode assembly to an aging treatment for progressing an initial creep of a cell module; a moisture content managing step (steps S120, 150) in which, in the plurality of the aging-treated modules, a moisture content in each of the membrane electrode assemblies is managed to fall in a value within a predetermined range; a lamination step (steps S160, 170, 180) in which the moisture content-managed cell modules are laminated in an environment in which the moisture content is managed; and a combining step (S190) in which the plurality of the laminated cell modules are combined by using a predetermined combining member in such a condition that a predetermined load is added to a lamination direction of the plurality of cell modules. <P>COPYRIGHT: (C)2009,JPO&INPIT |
