<P>PROBLEM TO BE SOLVED: To raise voltage, to suppress a heat generation rate, and to prevent the generation of drying, by decreasing current density in a module near to the inlet side of hydrogen gas in a fuel cell stack. <P>SOLUTION: A fuel cell device has a plurality of modules 10 formed by stacking a fuel cell interposing an electrolyte layer between a fuel electrode and an oxygen electrode, through a separator in which a fuel gas passage is formed along the fuel electrode, and the cell module 10 is a conductive, fuel gas passages in the cell module 10 are connected to each other so as to fold back for every module 10, and the current density of a cell module 10-1 positioned in a place where the probability of generating drying is high is made lower than that of other cell modules 10-2. <P>COPYRIGHT: (C)2007,JPO&INPIT |
