摘要： A fuel cell system includes a fuel cell, a control valve and a controller. The controller controls the control valve to periodically increase and decrease the anode gas pressure downstream of the control valve. The controller executes a shutdown/restart operation of the fuel cell by closing the control valve to stop the anode gas and shutting down power generation of the fuel cell upon receiving a shutdown command, and restarting feeding of the anode gas and restarting the power generation upon a prescribed operation restart condition being met. The controller estimates an anode gas concentration at a location where the anode gas concentration is locally lower within a power generation region of the fuel cell based on a control state of the anode gas when the shutdown command is issued. The controller sets the prescribed operation restart condition for executing the shutdown/restart operation based on the anode gas concentration.

摘要： A fuel cell system includes a battery, a fuel cell configured to generate power in accordance with a load, an inverter configured to convert power output from the fuel cell into alternating-current power and supply the alternating-current power to a motor, and a converter configured to control voltage between the inverter and the fuel cell using power output from the battery. The fuel cell system includes a voltage control unit configured to control the converter such that the voltage between the inverter and the fuel cell does not fall below a voltage lower limit of the inverter, and a lower limit voltage control unit configured to, when power required by the motor increases, cause the voltage between the inverter and the fuel cell to fall below the voltage lower limit of the inverter.

摘要： A fuel cell system supplies a fuel and an oxidant and outputs a generated power from the fuel cell to a secondary battery. In a method for controlling the fuel cell system, a charged amount of the secondary battery is acquired, when the charged amount of the secondary battery becomes equal to or less than a prescribed value, the fuel cell is started up from a state that the fuel cell stops power generation, or the generated power of the fuel cell is increased. In the method for controlling, a remaining amount of the fuel which can be supplied to the fuel cell is acquired and when the remaining amount of the fuel becomes small, the prescribed value is set to a smaller value as compared with when the remaining amount of the fuel is large.
