Beschreibung
Zusammenfassung:	A fuel cell vehicle may include: a fuel cell stack configured to generate electric power for a traction motor; a compressor configured to supply air to the fuel cell stack, the compressor including an impeller and a motor configured to rotate the impeller; and a controller configured to decrease a rotation speed of the motor when detecting accelerator-off. The controller may be configured to decrease the rotation speed at a first deceleration rate when an air outlet pressure of the compressor is higher than a pressure threshold, and decrease the rotation speed at a second deceleration rate when the air outlet pressure of the compressor is lower than the pressure threshold, the second deceleration rate being lower than the first deceleration rate.
