FUEL CELL GENERATING DEVICE

PROBLEM TO BE SOLVED: To provide a fuel cell generating device that prevents the trouble of reserved water flowing out totally from the steam separator at the time of the stoppage of the device and simplifies the blowdown circuit as well as reducing total cost. SOLUTION: The fuel cell generating device comprises a fuel cell body 1 which is mounted with a cooling plate flowing cooling water, a steam separator 5 separating the hot cooling water discharged from the cooling plate into steam and water and a generated water collector 7 for collecting the water generated in the fuel cell. The steam separator 5 is equipped with a blowdown circuit 100, which discharges the internal reserved water to the generated water collector 7. And the blowdown circuit is equipped with a blowdown water pressure control means having a thin pipe 10 of a smaller pipe sectional area than the main pipe of the circuit. A blowdown water drainage port 13 discharging into the generated water collector is installed at a higher position than a water level control position 12.
