PURPOSE: To always efficiently operate a fuel battery at a constant rated output when electric power is supplied to a plurality of loads by taking out multiple outputs from the output of the fuel battery.
CONSTITUTION: Two outputs are taken out from the output of a fuel battery 1 and the two outputs are respectively supplied to two loads 30 and 31 through inverters 20 and 21. The battery 1 is operated in a linked state with a commercial power source 4 against at least one load 30 and the inputs of the inverters 20 and 21 against the loads 30 and 31, the output of the inverter 20 on the linked side, and the output of the battery 1 are detected by means of power detecting means 11, 12, 13, 22 and inputted to a control circuit 5. The circuit 4 changes the load sharing ratio between the inverters 20 and 21 and the commercial power source 4 by controlling the outputs of the inverters 20 and 21 so that the output of the battery 1 can be maintained at a fixed level and the electric power required for compensating the variation of the loads can be supplied from the commercial power source 4.
