To provide a fuel cell vehicle in which startability is improved by reducing fluctuation of impedance immediately after start under the freezing point, and to provide a setting method of sweep time when stopped of the vehicle.SOLUTION: A fuel cell vehicle comprises a fuel cell stack 16 equipped with a cathode passage 38 and an anode passage 36, atmospheric pressure acquisition means 61 for acquiring the atmospheric pressure Pa, and a pump 26 for sucking the atmosphere and supplying oxidant gas to the cathode passage 38 through a feed passage 114. When it is predicted that the temperature goes below freezing after shutdown of the fuel cell stack 16, and the cathode passage 38 is swept by oxidant gas so that the cathode passage 38 is brought into a prescribed wet state, sweep time St during operation stop is set on the basis of the atmospheric pressure Pa.SELECTED DRAWING: Figure 1

    【課題】氷点下起動直後のインピーダンスのばらつきを少なくして起動性を向上させた燃料電池車両及び該車両の停止時掃気時間の設定方法を提供する。【解決手段】カソード流路38とアノード流路36を備える燃料電池スタック16と、大気の圧力Paを取得する大気圧取得手段61と、前記大気を吸込み、供給路114を通じてカソード流路38に酸化剤ガスを供給するポンプ26と、燃料電池スタック16の運転停止時以降に、氷点下になることが予測される場合、カソード流路38が所定の湿潤状態となるように酸化剤ガスによりカソード流路38を掃気するとき、大気圧Paに基づき運転停止時の掃気時間Stを設定する。【選択図】図1
