Abstract:
A fuel cell control system comprising at least one fuel cell having an anode and a cathode, comprising;an air supplying compressor, provided on an air-intake side of said fuel cell, for supplying pressurized air to an inlet of a cathode of said fuel cell, a pressure regulating valve, provided on an air discharging side of said fuel call, for regulating pressure of reactant gas discharged from said cathode of said fuel cell, a control means for deciding a target electric power of said fuel cell when a present target electric power of said fuel cell is changed, said control means for deciding and calculating a control amount of said air supplying compressor and a control amount of said pressure regulating valve on the basis of the target electric power of fuel cell, said control means for changing the control amount of said air supplying compressor at the onset of when said target electric power of fuel cell is changed, and, said control means for changing the control amount of said pressure regulating valve so as to adjust a pressure of air at the inlet of the cathode of said fuel cell to a suitable value after a predetermined time has passed when the control amount of said air supplying compressor starts to be changed.
