摘要： A fuel cell system includes a converter for boosting the output voltage of a fuel cell stack and supplies the boosted voltage to a first inverter for a drive motor and a second inverter for an air compressor motor, voltage acquisition means, and converter control means. The voltage acquisition means acquires a required voltage of the air compressor motor according to a target air compressor motor torque based on acceleration demand of the air compressor motor. The converter control means sets the voltage boost ratio of the converter and controls the converter by comparing the required voltage of the air compressor motor and a required voltage of the drive motor.

摘要： A fuel cell system (100) includes two supply passages (30, 32) for supplying the hydrogen to the anode (14). Valves (22, 23) which control flow amounts of the hydrogen passing through the two supply passages (30, 32) are provided. An exhaust passage (34) which outputs exhaust gas from the anode (14) is provided on the supply passage, and a valve (24) is also provided. When the valve (24) on the exhaust passage (34) is closed, the flow amount ratios of the hydrogen passing through the two supply passages (30, 32) are varied in time. Therefore, impurities such as nitrogen can be diffused. Thereby, a hydrogen purge amount can be reduced.

摘要： The pressure-adjusting valve provided in the cathode outlet of a fuel cell stack constituting a fuel cell system has a function of adjusting the oxidizing gas pressure in the fuel cell stack according to the adjustment of the valve opening degree. When the exhaust pipe is flooded with water, the pressure inside the exhaust pipe varies from the atmospheric pressure and the opening degree of the pressure-adjusting valve changes. The flooding estimation signal output processing unit of the control unit outputs a flooding estimation signal indicating that the exhaust pipe is flooded when an opening degree difference that is a difference between the opening degree of the pressure-adjusting valve and a preset opening degree corresponding to the operation directed pressure is equal to or greater than a preset threshold opening degree difference. The processing of inhibiting the flowing is performed based on this signal.
