摘要： A fuel cell system FC replenishes a fuel cell stack with air or hydrogen by temporarily driving a compressor or a low-pressure valve even during an intermittent operation mode. If air is supplied for replenishment, the amount of air remaining in an air supply system is kept substantially constant, so that the voltage fall during a stop of the fuel cell system can be curbed. If hydrogen is supplied for replenishment, the amount of hydrogen moving to the air supply system is offset, so that a delay in supplying hydrogen can be curbed. Furthermore, the fuel cell system FC inputs signals from a sensor, such as, a brake sensor, a shift selector, or other suitable means and anticipates acceleration of a vehicle equipped with the system FC. On the basis of the anticipation of acceleration, the system FC replenishes the fuel cell stack with air or hydrogen in advance.

摘要： 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).
