Abstract
The present invention provides a small fuel cell system including a secondary battery, in which deterioration in the secondary battery is suppressed regardless of a temperature condition. A control unit adjusts the supply amount of a liquid fluid of a fuel pump so that charging current Ito a secondary battery becomes smaller than a predetermined maximum charging current value Imax. Consequently, for example, even in the case of using a small secondary battery, the charging current Iis limited to be smaller than a predetermined upper limit value (maximum charging current value Imax). In addition, a temperature detecting unit detects temperature Tof the secondary battery and the control unit controls the maximum charging current value Imax in accordance with the detected temperature Tof the secondary battery. In such a manner, the operation of limiting the charging current Iin accordance with the temperature Tof the secondary battery at that time is performed.
