<P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of continuing stable power generation when abnormal instantaneous voltage drop is generated in system power source voltage. <P>SOLUTION: The fuel cll system is equipped with a fuel cell 11; a DC-AC conversion means 12 converting DC power from the fuel cell into AC power and supplying the AC power to a domestic load 13 along with the system power source; an operation control means 14 controlling a series of operation from starting to power generation; a system power source voltage measuring means 15 measuring the voltage waveform in the system power source; and a voltage waveform storage means 16 storing a power source voltage waveform. The operation control means 14 measures the voltage waveform in the system power source with the system power source voltage measuring means 15, stores the voltage waveform with the voltage waveform storage means 16, detects the generation of instantaneous voltage drop in the system power source by comparing with data in the voltage waveform storage means 16, and preferentially controls decrease in output current corresponding to decrease in power source voltage. <P>COPYRIGHT: (C)2008,JPO&INPIT |
