<P>PROBLEM TO BE SOLVED: To provide a system effectively preventing the disadvantage of the operation of hydrogen manufacturing for a fuel cell, appropriately preventing the poisoning of a catalyst and the deterioration of devices by controlling a sulfur concentration in fuel supplied to a reformer, and urgently stopping the operation of a hydrogen manufacturing system when desulfurizing the function of a desulfurizer is lowered, in the manufacturing of hydrogen for the fuel cell. <P>SOLUTION: In a fuel cell system in which the desufurizer 2 desulfurizing fuel supplied from a vessel containing hydrocarbon fuel 1, a reformer 4, and a fuel cell stack 5 are sequentially installed, a detector 3 measuring a sulfur concentration is installed in the outlet of the desulfurizer 2, and when the sulfur concentration measured by the detector reaches a prescribed set concentration, a function of notifying the reach to the outside and/or a function of stopping the operation of the fuel cell system are contained. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
