<P>PROBLEM TO BE SOLVED: To provide a warming-up system of a fuel cell capable of reducing fuel consumption used for power generation for drive by driving a heating means with high-efficiency power of the fuel cell. <P>SOLUTION: This system is provided with a storage battery 13 for storing power generated by the fuel cell 12; when a fuel cell temperature sensor 9r detects a temperature below a predetermined value, and remaining electric energy of the storage battery 13 is small (less than a predetermined amount), an electric compressor 17 is driven by power generated by the fuel cell 12 and the storage battery 13 is charged; and when the remaining electric energy of the storage battery 13 is larger than the predetermined amount, the electric compressor 17 is driven by using the power of the storage battery 13. A cooling medium brought into a high-temperature and high-pressure condition by the electric compressor 17 heats cooling water in a second cooling water circulation passage 15b by a water-cooling medium heat exchanger 24, and the heated cooling water transmits heat to the fuel cell 12 during circulation in the fuel cell 12 to warm up the fuel cell 12. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
