To efficiently discharge exhaust gas from a cathode side flow path of a fuel cell, thus improving the efficiency of the whole vehicle.SOLUTION: At least a part of an underfloor portion of a vehicle body is shaped so that wind passing through the underfloor portion applies down force to the vehicle body. At a negative pressure region where negative pressure is generated by the shape that applies the down force, there is provided an air outlet for discharging exhaust gas from the cathode side flow path of the fuel cell. Magnitude of the negative pressure generated by the shape is detected or estimated, and the amount of drive of an air supplier for supplying air to a cathode of the fuel cell is controlled according to the detected or estimated magnitude of the negative pressure. Thus, the negative pressure is used to introduce the air into the cathode side flow path, allowing improvement in efficiency of the whole vehicle.SELECTED DRAWING: Figure 1

    【課題】燃料電池のカソード側流路からの排ガスを効率良く排出し、車両全体の効率を高める。【解決手段】車体の床下の少なくとも一部を、床下を通過する風により車体にダウンフォースを付与する形状とし、燃料電池のカソード側流路からの排ガスを排出する排気口を、ダウンフォースを付与する形状によって負圧が発生する負圧領域に配設する。この形状により発生する負圧の大きさを検出または推定し、検出または推定された負圧の大きさに応じて、燃料電池のカソードに空気を供給する空気供給器の駆動量を制御する。こうすることで、負圧を利用して、カソード側流路への空気の導入を図り、車両全体の効率を高めることができる。【選択図】図1
