摘要： The present invention provides a technique capable of satisfying both the restoration of an output voltage of a fuel cell and an improvement of electric power responsiveness in a fuel cell system in a situation in which its operation status is restored to a normal operation from an operation having low power generation efficiency.A controller updates a lower limit voltage threshold in accordance with the restoration of an FC voltage until the operation status is restored to a normal operation from an operation having low power generation efficiency, such as an intermittent operation and a warmup operation (step S1). The controller increases an FC current in accordance with the updated lower limit voltage threshold (steps S2 and S3) to thereby satisfy both the requirements of the restoration of the output voltage of the fuel cell stack and the improvement of the electric power responsiveness.

摘要： To provide a flying object capable of suppressing ignition of a secondary battery due to overcharging. A flying object includes a fuel cell, a secondary battery, a motor, an air resistance increasing device capable of increasing the air resistance, and a control unit. The motor drives a propulsion propeller. The fuel cell, the secondary battery, and the motor are electrically connected. The motor is driven by obtaining power from at least one of the fuel cell and the secondary battery. When the fuel cell generates an amount of power exceeding a power consumption amount, the control unit increases an amount of power supplied to the motor from the fuel cell while increasing the air resistance by operating the air resistance increasing device, and performs a power consumption control to maintain a flight state.

摘要： A fuel cell system includes: a fuel cell unit; a temperature acquiring unit acquiring an ambient temperature of a first fuel cell stack of the fuel cell unit; and a power generation control unit. The power generation control unit is configured to, when required power for the fuel cell unit is less than a predetermined threshold value, temporarily stop power generation of the first fuel cell stack and to switch the first fuel cell stack from stopped power generation to power generation when a continuous power generation stopped time of the first fuel cell stack is greater than a predetermined time such that the continuous power generation stopped time is shorter when the ambient temperature is equal to or lower than a predetermined temperature based on a temperature at which liquid water in the first fuel cell stack freezes than when the ambient temperature is higher than the predetermined temperature.
