Zusammenfassung: | PURPOSE:To continue operation of a fuel cell stably even if a power failure is caused in commercial electric power supply operated cooperatively with the fuel cell by arranging a means to switch electric power supply of an equipment for exhaust heat and ventilation from the commercial electric power supply to the fuel cell when the power failure is caused in the commercial electric power supply. CONSTITUTION:When voltage of commercial electric power supply 22 is lowered, the voltage drop is detected by a lacking voltage detector 15, and a signal is transmitted to a timer 16. When a voltage drop condition continues over prescribed time, respective switches 17-19 for a cooling water pump 11, a cooling tower 12 and a fan 13 are opened simultaneously by a signal from the timer 16. In succession, a double-throw switch 20 is switched to a contact point (b) (fuel cell 1 side) from a contact point (a) (commercial electric power supply 22 side) so far. Afterwards, the switches 17-19 are closed successively. |
