Abstract
A fuel cell vehicle includes a battery and a cell stack including a plurality of unit cells stacked one above another. The fuel cell vehicle also includes a boost converter configured to boost and output a target voltage received from the cell stack in response to a switching signal. The fuel cell vehicle further includes a switching unit configured to be switched in response to a control signal to connect an output side of the boost converter to the battery. The fuel cell vehicle additionally includes a controller configured to generate the control signal when startup of the fuel cell vehicle is requested. The controller is also configured to vary a switching frequency of the switching signal in response to a difference between a first voltage output from the cell stack and a second voltage of the battery.
