FUEL CELL VEHICLE, METHOD OF CONTROLLING STARTUP THEREOF, AND RECORDING MEDIUM STORING PROGRAM TO EXECUTE THE METHOD

A fuel cell vehicle of the disclosure includes a cell stack, a boost converter receiving a first target voltage from the cell stack, a supercapacitor, an initial charging converter receiving a second target voltage from the cell stack, a first switching unit configured to be switched in response to a first control signal to connect an output side of the boost converter to the supercapacitor, a second switching unit configured to be switched in response to a second control signal to connect an output side of the cell stack to the initial charging converter, and a controller configured to generate the first and second control signals in order to connect the output side of the boost converter to the supercapacitor while the output from the initial charging converter is charged in the supercapacitor so that the supercapacitor is charged until startup is completed by receiving the first target voltage.
