PROBLEM TO BE SOLVED: To provide a power supply system capable of suppressing a use amount of fuel to be used for power generation of a fuel cell as much as possible, while efficiently supplying power from the fuel cell to a load.SOLUTION: A power supply system performs charging/discharging on a storage battery device 30 on the basis of power consumption of a load to make the value of power generated by a fuel cell 20 be any one of a plurality of rated values, and supplies power from a commercial power supply 90, the fuel cell 20, and the storage battery device 30 to the load. The power supply system comprises a controller 50 for updating a first rated value P1, which is one of the plurality of rated values and is a value capable of being updated, by replacing a first rated value P1(n) with a first rated value P1(n+1) depending on the existence of residual power stored in the storage battery device 30 at the time of the end of the previous day prior to the day on which the update is performed.SELECTED DRAWING: Figure 1 |
