Abstract:
The present disclosure is made in order to reduce inaccuracy of current sensors. A fuel cell system  100  comprises a converter  150  configured to convert output voltage of the fuel cell  1,  and a current sensor CS 1  including a preliminarily magnetized magnetic core MC 1  and configured to measure current flowing in the converter  150  from the fuel cell  1.  A controller  160  comprises, as driving modes of the fuel cell system  100,  a first driving mode DM 1  in which a maximum current value IL1max in a target circuit of current measurement by the current sensor CS 1  is lower than a current value for preliminary magnetization of the magnetic core and a second driving mode DM 2  in which the maximum current value IL2max in the target circuit is higher than the maximum current value IL1max in the target circuit in the first driving mode DM 1.  When an accumulated temperature value IT of the current sensor CS 1  in the first driving mode DM 1  has exceeded a threshold ITth, the second driving mode DM 2  is executed and subsequently the first driving mode DM 1  is executed.

Claim (Index 3):
The fuel cell system according to  claim 2 , wherein\n a rest of the plurality of circuits forming the multiple phases except for the circuit connected to the fuel cell via the target circuit also comprise current sensors comprising preliminarily magnetized magnetic cores and configured to measure the current flowing in the circuits from the fuel cell, and wherein the controller is configured to choose at least one of the plurality of circuits that is unfixed as the one or more circuits to be used in the second driving mode when the number of the one or more circuits to be used is smaller than a maximum number of the plurality of circuits forming the multiple phases, and when the accumulated temperature values of two or more of the current sensors have exceeded the threshold and the number of the one or more circuits to be used is smaller than a maximum number, the controller uses the one or more circuits including at least one circuit preferentially chosen from among circuits equipped with the two or more of the current sensors in order of the accumulated temperature value from highest to lowest and uses the at least one of the plurality of circuits in the second driving mode.
