PROBLEM TO BE SOLVED: To provide an air intake structure capable of effectively preventing intrusion of water and the like, even when an air inlet port is provided in a front portion of a fuel cell vehicle.SOLUTION: An air intake structure 3 used for a fuel cell vehicle B equipped with a fuel cell 11 in a front space M of the vehicle, the air intake structure comprising: an air inlet port 31 disposed in a front portion of the front space M; an air passage 33a through which air flows from the air inlet port 31 to the fuel cell 11; and a water separation passage 33b that branches downward from a branch point in a middle of the air passage 33a to separate water entrained in the air, the water separation passage having a downstream opening 34 on a downstream side in the front space. A minimum passage sectional area of the air passage 33a located downstream of the branch point is larger than a minimum passage sectional area of the water separation passage.SELECTED DRAWING: Figure 4

    【課題】燃料電池車の前方部に空気吸気口を設けた場合でも、水などが入り込むのを有効に防止することができるエアインテーク構造体を提供すること。【解決手段】車両Bの前部空間M内に燃料電池11が配置される燃料電池車に用いるエアインテーク構造体3であって、前部空間M内の前方部に配置された空気吸気口31と、空気吸気口31から燃料電池11に向かう空気が通流する空気流路33aと、空気流路33aの途中の分岐点から下方に分岐し、空気に同伴する水を分離し、下流側の下流開口34が前部空間内に配置された水分離流路33bと、を備え、分岐点よりも下流の空気流路33aの最小流路断面積は、水分離流路の最小流路断面積よりも大きい。【選択図】図4
