<P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of performing restarting smoothly even if the fuel cell system has stopped for a long time. <P>SOLUTION: The fuel cell system 1 comprises a fuel cell 10, a hydrogen supply source 22, a cut-off valve 251, and an air compressor 21 for supplying a reaction gas to the fuel cell 10, a purge valve 261, a backpressure valve 241, and an air inlet valve for supplying air and scavenging, a control part 31 including a monitoring part, and a battery 34. The monitoring part judges whether or not the temperature of the fuel cell 10 is a prescribed value or less. The control part 31 has a scavenging judgement part which performs a scavenging treatment when it is judged by the monitoring part that the temperature is the prescribed value or less, a final treatment judgement part which judges final treatment of the fuel cell 10, and an energy amount judgement part which judges whether or not the energy amount of the battery 34 is sufficient for monitoring the fuel cell 10 and, if judged that it is sufficient, starts the monitoring part, and, if judged that it is not sufficient, starts the final treatment judgement part. <P>COPYRIGHT: (C)2007,JPO&INPIT |
