Abstract
A fuel cell system includes fuel cell, an electrical storage device that stores electric power generated by the fuel cell, and a control device that controls generation of power by the fuel cell, that acquires a charging rate of the electrical storage device, when the electric power in the electrical storage device is supplied to external devices, the control device performs first control which increases a charging rate of the electrical storage device and second control which restricts a power generation amount of the fuel cell to be smaller than in the first control and decreases a charging rate of the electrical storage device, and when a temperature detected by the temperature sensor is lower than a predetermined temperature, a power generation amount per hour of the fuel cell in the first control is reduced in comparison when the detected temperature is equal to or greater than the predetermined temperature.
