<P>PROBLEM TO BE SOLVED: To provide a fuel cell system that is advantageous to suppress freezing of a drain section farther downstream than a condensed water tank in which the condensed water is stored. <P>SOLUTION: The system includes a fuel cell 1; the condensed water tank 30 for storing the condensed water generated in accordance with a power generation operation of the fuel cell 1; the drain section 32 for discharging surplus water in the condensed water tank 30 to the outside; a hot water storage system 130 that has a hot-water storage vessel 131 for storing the hot water heated by the heat generated accompanying the power generation operation of the fuel cell 1; a hot-water passage 50 capable of supplying heat energy of the hot water in the hot-water storage system 130 to the drain section 32, and a hot-water valve 52. When there is a possibility that the drain section 32 may be frozen, or when the drain part 32 is frozen, the control part 5 makes the hot-water valve 52 released and supplies the heat energy of the hot water in thehot-water storage system 130 to the drain section 32 via the hot-water passage 50, and suppress freezing of the drain section 32. <P>COPYRIGHT: (C)2011,JPO&INPIT |
