PURPOSE:To reduce the voltage fluctuation of a fuel cell caused through the load variation by providing a control speed lagged behind that of gas flow or air flow to an inverter as a load command. CONSTITUTION:A load command 6 is processed by an arithmetic unit 5 to produce an output which is fed to a valve 2 thus to vary the gas flow through a gas conduit 1 and to feed to a fuel cell 3 while the output of said cell 3 is varied and converted through an inverter 4 into A.C. power. The load command 6 is operated by an arithmetic unit 7 such that it will be lagged behind the control speed of gas flow and fed as a control signal to the inverter 4. When lagging the control signal of inverter 4 behind the gas flow control signal, voltage fluctuation of the fuell cell 3 due to the load variation can be reduced resulting in elimination of influence onto the cell 3. |
