<P>PROBLEM TO BE SOLVED: To provide a desulfurization system with which the deterioration of the reforming performance of a fuel cell system is prevented and an increase in control loads and cost of the whole system can be suppressed. <P>SOLUTION: The deterioration of the reforming performance of a fuel cell system 100 is prevented by surely controlling the flow rate of a liquid fuel allowed to flow in a reforming device 2 by reducing the pressure of the liquid fuel, desulfurized in a desulfurizer 13, in an oil storage tank 14. Further, an overflow line 16 whose one end is connected to an upper limit position FT of the oil storage tank 14 and a liquid fuel storage tank 11 connected to the other end of the overflow line 16 and storing the liquid fuel overflowed from the oil storage tank 14 are provided. Thereby, it becomes possible to pool the overflowed liquid fuel into the liquid fuel storage tank 11 through the overflow line 16 when the liquid surface in the oil storage tank 14 reaches above a certain level without attaching a sensor to the upper limit position FT and without controlling the flow rate by detecting the liquid surface. <P>COPYRIGHT: (C)2010,JPO&INPIT |
