PROBLEM TO BE SOLVED: To maintain appropriate output control of a fuel cell even if a current sensor provided for each phase of a multiphase converter fails.SOLUTION: A fuel cell system 1 includes a fuel cell 100, a multiphase converter 120, and current sensors I1-I4 provided in phases of the multiphase converter 120, respectively. In the fuel cell system 1, the total value of current values of the phases detected by the current sensors I1-I4, respectively, is controlled as the output current of the fuel cell 100. The fuel cell system 1 is further provided with control means 200 for, when abnormality of the current sensors I1-I4 in some phase is detected by abnormality detection means, stopping the driving of the abnormal phase and setting the total value of current values detected by the current sensors I1-I4 provided in the other phases excepting the abnormal phase as a target output current of the fuel cell 100. |
