PROBLEM TO BE SOLVED: To provide a control method, etc., capable of suppressing a reduction in the power generation efficiency of a fuel cell.SOLUTION: Provided is a method of controlling a power supply device connected to a wiring for electrically connecting a utility grid and a power load at a place closer to the utility grid than to a connection point where a fuel cell is connected and an installation point where the current sensor of the fuel cell is installed, and a power branching device connected to the wiring at a place closer to the power load than to the connection point where the fuel cell is connected, wherein, when power consumption by the power load is less than or equal to the output power of the fuel cell, this power control method causes prescribed power to be outputted to the wiring by the power supply device and excess power among the power outputted to the power branching device from the power supply device and the fuel cell to be branched from the wiring. |
