<P>PROBLEM TO BE SOLVED: To provide a solid oxide fuel cell system capable of suppressing reduction in condensation efficiency of steam in an exhaust gas and external exhaust of this steam, and capable of suppressing shortage of reformed water. <P>SOLUTION: The solid oxide fuel cell system is equipped with a reformer 4 to steam reform a raw material fuel, a solid oxide fuel cell 6 to carry out power generation by oxidization and reduction of a reformed fuel gas and an oxidizing material, a blower 8 to send the oxidizing material to the solid oxide fuel cell 6, a flow rate control valve 34 to control a supply amount of the raw material fuel, a control means in order to control operation of the flow rate control valve 34 and the blower 8, a condensation recovery means 50 to condensate steam in the exhaust gas, a water recovery tank 51 in order to store water condensed by the condensation recovery means 50, and a water sending and supplying means 52 in order to send water in the water recovery tank 51 to the reformer 4. When a water level of water in the water recovery tank 51 is reduced to a low water level, the control means switches from operation of a normal operation mode to operation of a water recovery operation mode. <P>COPYRIGHT: (C)2011,JPO&INPIT |
