Title: Overcurrent detecting device of fuel cell generating set
Inventor: ITO MAKOTO
IPC: H01M8/04
Filed: 1998-07-01
Abstract: PROBLEM TO BE SOLVED: To stably supply electric power by eliminating unwanted stopping of a generating set by providing a means for detecting time, when a direct current of a fuel cell inputted to a power inverter for outputting the direct current to an electric power system, after being converted into an alternating current of a commercial frequency is not less than a preset value and DC electric power does not increase at least as an overcurrent state. SOLUTION: A direct current from an electric current detector 4, such as a current transformer between a fuel cell 1 and a power inverter 2 and DC electric power arithmetically operated by an electric power computing device 6 from the direct current and DC voltage detected by a voltage detector 5, are inputted to an overcurrent detector 7. When the direct current is not less than a preset value and the DC electric power is not more than the last time value, it is considered as being in an overcurrent state. A device may be so constituted as to be decided it as being in overcurrent state, even if the DC electric power does not fluctuate, when the direct current exceeds a second preset value not less than this preset value.  Thus, a generating set being stopped when overcurrent of damaging the fuel cell 1 occurs, since there is no possibility of returning to a voltage drop due to lack of fuel gas, so that temporary overcurrent by system disturbance or the like is not detected.
