The control device, under a tendency that power consumption of a load at least connected with the fuel cell and the power storage device decreases, determines a first lower limit power based on power generated by the fuel cell before a predetermined time, causes the fuel cell to generate second power equal to or greater than the first lower limit power when first power generated by the fuel cell determined based on a power supplied to the load drops below the first lower limit power, and determines the first lower limit power with a tendency that the greater the generated power, the greater a difference between the generated power and the first lower limit power is increased.

Abstract: An ECU of a fuel cell system determines whether or not temperature information exceeds a temperature threshold for determination when receiving a signal related to power generation stop of a fuel cell stack during operation of a moving body. When the temperature information exceeds the determination temperature threshold, the ECU performs a stop control for stopping power generation of the fuel cell stack. On the other hand, when the temperature information is equal to or lower than the determination temperature threshold, the ECU performs an idle control for generating electric power smaller than electric power consumed by the air pump.

Abstract: During startup of a fuel cell system, feed forward control is performed to increase the rotation number of an electric auxiliary device (compressor) to a modified steady state rotation number while maintaining a steady state rotation acceleration rate of the electric auxiliary device. In this manner, the overshoot amount is suppressed to an allowable overshoot amount. Otherwise, feed forward control is performed to increase the rotation number of the electric auxiliary device to a modified low steady state rotation number while maintaining a low steady state rotation acceleration rate. In this manner, the overshoot amount is suppressed to an allowable overshoot amount.
