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： In a fuel cell system of the invention, a pressure regulator is provided in the pathway of a hydrogen supply conduit that connects a hydrogen tank to a fuel cell stack. An anode off gas discharged from the fuel cell stack is recirculated through a recirculation pipe into the hydrogen supply conduit. A hydrogen pump is provided in the pathway of the recirculation pipe to increase the pressure of the anode off gas. A control unit of the fuel cell system includes a hydrogen pump control module, an abnormality diagnosis module, and an atmospheric pressure-based correction module. The hydrogen pump control module regulates the rotation speed of the hydrogen pump corresponding to a power demand to be output from the fuel cell system. The abnormality diagnosis module detects an abnormal state, based on a result of determination of whether the pressure of the hydrogen supply measured by a pressure sensor is within a certain range defined by two preset threshold values. The atmospheric pressure-based correction module corrects the rotation speed of the hydrogen pump and the threshold values used for abnormality diagnosis according to the atmospheric pressure measured by an atmospheric pressure sensor. Even in the state of unstable output of the pressure regulator with a variation of the atmospheric pressure, such correction compensates for the varying flow rate of the hydrogen supply to the fuel cell stack and thus effectively prevents misjudgment of abnormality diagnosis. Namely the technique of the invention reduces the potential effect of the varying pressure of the hydrogen supply to the fuel cell system with a variation of the atmospheric pressure.
