<P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of elongating a life of a secondary battery by avoiding over-charge of the secondary battery. <P>SOLUTION: A fuel cell system 10 comprises: a cell stack 12; a secondary battery 66; auxiliary machines 90 and a heater 30 electrically connected to the cell stack 12 and the secondary battery 66; and a CPU 52 for controlling an operation state of the fuel cell system 10. The CPU 52 controls the operation state of the fuel cell system 10 to any of a stop state that power generation of the cell stack 12 is stopped, and a temperature-rising state that the power is generated to the cell stack 12 to increase the temperature of the cell stack 12. Under the temperature-rising state, power generated by the cell stack 12 is consumed by the auxiliary machines 90 and the heater 30, and therefore, the secondary battery 66 is not charged. <P>COPYRIGHT: (C)2013,JPO&INPIT |
