<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a fuel cell capable of improving power generation efficiency. <P>SOLUTION: The method of manufacturing the fuel cell comprises a first process in which a plurality of porous bodies to be incorporated in gas passages 26, 28 in a fuel cell stack 10 are prepared, a second process to select the porous bodies 30 based on weight, and a third process to manufacture the fuel cell stack 10 using the selected porous bodies 30. Since there is a correlation between the weight of the porous bodies 30 and ventilation resistance of gas, it becomes possible to unify the ventilation resistance of gas by selecting the porous bodies 30 based on weight, thereby power generation efficiency can be improved. <P>COPYRIGHT: (C)2007,JPO&INPIT |
