PURPOSE: To provide a fuel cell generating plant in which the operation can be continued without changing the operating temperature of a fuel cell body even when the steam supply to a steam utilizing system is stopped by failure and the capacity of a heat exchanger can be minimized. CONSTITUTION: This fuel cell generating plant has a fuel cell body cooling system for circulating a cooling water for cooling the reaction heating in a fuel cell body 1 through a steam separator 2 and a means 8 for supplying the steam generated in the steam separator 2 to a steam utilizing system. It also has a steam treatment device 9 capable of taking out the steam in the steam separator 2 independently from the fuel cell body cooling system and the steam utilizing system, so that the excessive steam of the steam separator 2 can be taken out by the steam treatment device 9 when the steam supply to the steam utilizing system is stopped. When the temperature of the fuel cell body is lowered by the stop, the steam of the steam separator 2 is discharged to the steam treatment device 9 to enhance the heat exchanging ratio. |
