Abstract

PURPOSE:To carry out a wide range of highly accurate control by operating a switch element when output is over a given value, and using a main valve, which is used as a fuel supply system, when the output is large instead of using an auxiliary valve used when the output is small. CONSTITUTION:Fuel is supplied to a fuel cell 2 from a fuel supplying device 1 through an auxiliary valve 32 and a main valve 31. The temperature of the cell 2 is regulated by detecting it with a detector 4, the output voltage is passed through a PID voltage controlling circuit 61 so as to regulated the auxiliary valve 32, and the output current is passed through a compensating amplifying circuit 71 so as to regulated the main valve 31. When the output of the circuit 71 reaches 5-20% of the output of the cell 2, switches 64 and 74 are operated and released by means of a comparator 81. Consequently, highly accurate control can be carried out constantly by operating the auxiliary valve 32 during the time of small output.
