    • A DC/DC converter includes a reactor, IGBT devices, a dead time generation unit, and a DC-CPU. The dead time generation unit operates in response to a reference signal for a duty ratio, to output first and second activation signals provided with an inactive period corresponding to a dead time preventing both of the IGBT devices from conducting. The DC-CPU corrects a tentative duty ratio calculated as based on a voltage control value, in accordance with a value of a current flowing through the reactor, to output the reference signal. Preferably the DC-CPU associates the value of the current of the reactor with three states and when the value approaches a value at which a state transitions to a different state, the DC-CPU gradually switches a correction value.

    • A fuel cell system according to the present invention is characterized by comprising a measurement unit which measures an impedance of a fuel cell in a predetermined frequency region, and a regulation unit which regulates an amount of a gas to be supplied to the fuel cell based on a measured value of the impedance in the predetermined frequency region. According to such a constitution, the impedance of the fuel cell in the predetermined frequency region (e.g., a low frequency region) is measured, and the amount of the gas (e.g., an amount of an oxidizing gas) to be supplied to the fuel cell is regulated based on this measured value of the impedance. Here, since the impedance of the fuel cell in the predetermined frequency region largely differs with a fuel supply state (see FIG. 2), the amount of the gas to be supplied to the fuel cell can be regulated based on the measured value of the impedance to realize a highly efficient and stable operation.

    • The measurement precision of a current detector of the fuel cell in a fuel cell system is improved. Where the fuel cell system 20 has not started operation, the vehicle 10 is operating under regenerative operation, the fuel cell 21 is operating under intermittent operation, or operation of the fuel cell system 20 has ended, the output terminal voltage of the fuel cell 21 is set to the OCV value of 400V via the DC/DC converter 31. As a result, even where the status of the fuel cell 21 changes from operating to stopped, the value of the current flowing over the power supply lines 411 can be immediately and reliably set to 0 A. The control unit 60 then obtains the current value Ad from the fuel cell current sensor 413 (step S150), and determines the offset correction value Ac needed in order to cancel the drift amount (i.e., in order to perform zero-point correction).
