An extended-range fuel cell electric vehicle power device includes a driving motor, a bidirectional converter, a chopper, a power cell, a fuel cell, a high-pressure hydrogen storage tank, an electric control valve, a controller, an accelerator pedal and a brake pedal. An output of the driving motor is connected to a transmission shaft of an electric vehicle through a speed change gearbox, and an input of the driving motor is connected to an alternating current output end of the bidirectional converter; a direct current input end of the bidirectional converter is connected in parallel to an output of the power cell and an output of the chopper, and an input of the chopper is connected to a power source output of the fuel cell.
