Abstract
A fuel cell vehicle is configured such that at least a part of an underfloor of a vehicle body is formed to have a shape causing a downforce to the vehicle body by wind passing below the underfloor, and an exhaust port via which exhaust gas from a cathode-side passage of a fuel cell is discharged is disposed in a negative pressure region where a negative pressure is caused by the shape causing the downforce. A magnitude of the negative pressure to be caused by the shape is detected or estimated, so that a driving amount of an air supply configured to supply air to the fuel cell is controlled according to the magnitude of the negative pressure thus detected or estimated.
