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 6):
The method for controlling the fuel cell system according to  claim 5 , wherein\n the converter comprises a plurality of circuits connected in parallel to each other to form multiple phases, wherein the target circuit connects one of the plurality of circuits forming the multiple phases and the fuel cell, and wherein in the step (b), when compared on a condition that electric power required from the fuel cell is equal, one or more circuits from among the plurality of circuits forming the multiple phases are used to drive the converter, wherein number of the one or more circuits to be used in the step (b) is smaller than number of circuits used in the step (a) and the one or more circuits to be used comprises at least one of the plurality of circuits in which the accumulated temperature value of the current sensor has exceeded the threshold.
