PROBLEM TO BE SOLVED: To suppress the life of a secondary battery from expiring in an early stage, in a power supply unit including a fuel cell and the secondary battery.SOLUTION: At least one power of input power input from a fuel cell 5 to a secondary battery 9 and output power output from the secondary battery 9 is controlled on the basis of a detected temperature T1 detected by a thermometer 11C for detecting the temperature Tb of the secondary battery 9. As a result, the secondary battery 9 can be maintained in a proper temperature range, so that the life of the secondary battery 9 can be suppressed from expiring in an early stage. |
