A fuel cell vehicle capable of improving energy efficiency by reducing switching loss is provided. The fuel cell vehicle includes: a fuel cell that generates direct current power; inverters which respectively include switching elements and convert the direct current power generated by the fuel cell into alternating current power; a diode that prevents current from flowing from the inverters toward the fuel cell; a step up/down DC/DC converter that adjusts the voltage of the cathode side of the diode; a voltage control part that controls the step up/down DC/DC converter, thereby controlling current output from the fuel cell; and a stop and idle determination part that stops the supply of air to the fuel cell, thereby stopping idling of the fuel cell. The voltage control part reduces the voltage of the cathode side of the diode as the voltage of the fuel cell is reduced by activating the stop and idle determination part. |
