    Abstract: A fuel cell system includes a fuel cell, a plurality of power consuming devices, a secondary battery, a charge-discharge amount sensor, and a controller configured to control operations of the plurality of power consuming devices. An identification section of the controller is configured to execute a variation process of varying the operation command value of one of the plurality of power consuming devices and, in a second case where an absolute value of a difference between an amount of change in the actual amount of charge and discharge and an amount of change in the estimated amount of charge and discharge before and after execution of the variation process is greater than a second threshold, identify the power consuming device, for which the operation command value is varied, as the device to be identified.

    Abstract: A control unit comprised in a fuel cell system is configured to perform prediction of whether a required output for a motor generator has a positive value and determination of whether a voltage of a fuel cell is less than a target voltage during execution of an auxiliary machine power consumption, and is configured to set a bypass valve to a first degree of opening during execution of the auxiliary machine power consumption when a result of at least one of the prediction and the determination is negative, and is configured to set the bypass valve to a second degree of opening less than the first degree of opening during execution of the auxiliary machine power consumption when results of both the prediction and the determination are positive.

    Abstract: A fuel cell system includes a fuel cell, a gas supply unit, an electric power storage device, a remaining capacity monitor, and a control unit. The control unit determines whether the temperature conditions are met, wherein the low temperature conditions include temperature related to a state of the fuel cell being equal to or lower than a predetermined threshold value set, when the control unit determines that the low temperature conditions are met, the control unit executes the purging process so as to discharge more of moisture stored in the fuel cell to an outside of the fuel cell, as compared with when the control unit determines that the low temperature conditions are not met, and the control unit executes the charging process with target remaining capacity of the electric power storage device set to a smaller value, as compared with when the control unit determines that the low temperature conditions are not met.

    Abstract: A fuel cell system mounted on a vehicle comprises a fuel cell; a secondary battery; a drive motor configured to serve as a motor to generate a driving force and as a generator to generate regenerative power; an auxiliary machine configured to consume the regenerative power; an accelerator pedal sensor; a shift position sensor; a vehicle speed sensor; and a controller. The controller determines that the vehicle is in a first state when the vehicle has a negative vehicle speed, a move forward request is given to the vehicle and an accelerator pedal is depressed or when the vehicle has a positive vehicle speed, the move backward request is given to the vehicle and the accelerator pedal is depressed. When a predetermined first condition including a condition that the vehicle is in the first state is satisfied, the controller performs an auxiliary machine consumption process that causes the auxiliary machine to consume the regenerative power that includes a required power for the drive motor calculated by using a depression amount of the accelerator pedal.

    Abstract: A fuel cell system includes a sensor. The controller decides a continuous rated electric power. The controller sets a time rated electric power as a final upper limit electric power when the time rated electric power is higher than the continuous rated electric power and is lower than an instantaneous upper limit electric power, and sets the instantaneous upper limit electric power as the final upper limit electric power when the time rated electric power is higher than the continuous rated electric power and is higher than the instantaneous upper limit electric power. When the time rated electric power is lower than the continuous rated electric power, the continuous rated electric power is set as the final upper limit electric power. The controller controls one of the boost converter and an FC such that the output of the boost converter does not exceed the final upper limit electric power.
