<P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of easily confirming leakage of fuel gas during replacement of a desulfurizer. <P>SOLUTION: The fuel cell device is equipped with: a fuel cell module in which a fuel cell 1 is housed; and a fuel gas supply device 11 for supplying hydrogen to the fuel cell module. The fuel gas supply device 11 is formed by connecting in order: the desulfurizer 6 for removing sulfur from hydrocarbon gas supplied from a hydrocarbon gas supply source; a gas pump 4 for pressure-feeding desulfurized hydrocarbon gas; a supply pressure adjuster 5 capable of reducing the supply pressure of pressure-fed hydrocarbon gas to the level of an original pressure of the hydrocarbon gas supply source; and a modifier 3 modifying the hydrocarbon gas whose supply gas is adjusted to hydrogen by using a fuel gas supply pipe 12. Therefore, when the desulfurizer 6 is replaced together with a container and connected again, leakage of the hydrocarbon gas from a joint of the desulfurizer 6 and the fuel gas supply pipe 12 can easily be confirmed. <P>COPYRIGHT: (C)2009,JPO&INPIT |
