<P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of controlling output current to be close to a sinusoidal waveform while measuring output current with output current measuring means when a failure of a commercial power voltage occurs. <P>SOLUTION: The fuel cell system comprises: converting means 12 connected to a commercial power supply for converting a direct-current power of the fuel cell 11 to an alternating-current power, and for supplying the alternating-current power to an in-home load 13 together with the commercial power supply; operation controlling means 14 for controlling a series of operations from activation to power generation; output current measuring means 15 for measuring a waveform of output current from the converting means 12; and commercial power voltage measuring means 16 for measuring a voltage waveform of the commercial power supply. The voltage waveform of the commercial power supply is measured by the commercial power voltage measuring means 16. If failure such as instantaneous voltage drop or voltage distortion occurs, then the operation controlling means 14 controls output current from the direct-current to alternating-current converting means 12 to be close to a sinusoidal waveform, while causing the output current measuring means 15 to measure the output current. <P>COPYRIGHT: (C)2007,JPO&INPIT |
