<P>PROBLEM TO BE SOLVED: To provide a fuel cell system which prevents the breakage of an inverter internal circuit caused by the generation of a reversed current in the inverter from a system power supply side. <P>SOLUTION: The fuel cell system is equipped with a DC-DC converter 12 to boost direct-current power generated by a fuel cell 11, the inverter 13 to convert the direct current power boosted by the DC-DC converter 12 into alternating current power, a linkage breaker 14 in order to link the alternating current power converted by the inverter 13 to a system power supply, a surplus converter 16 to consume direct current power boosted by the DC-DC converter 12 changed into heat by a heater 17, a DC-DC converter output voltage detecting means 18 to detect a direct current voltage boosted by the DC-DC converter 12, and an operation control means 19, and constituted so that the linkage breaker 14 carries out the parallel-off when a voltage detected by the DC-DC converter output voltage detecting means 18 reaches a prescribed voltage or lower. <P>COPYRIGHT: (C)2011,JPO&INPIT |
