To provide a technology capable of suppressing a problem caused by a large diameter of generated water discharged from a muffler of a fuel cell vehicle.SOLUTION: A muffler for a fuel cell vehicle includes a curved portion, forming a part of the muffler, attached to a vehicle equipped with a fuel cell, for discharging exhaust gas and generated water discharged from the fuel cell to an outside of the vehicle, having a small diameter portion and a large diameter portion having an outer diameter larger than the small diameter portion, and having an opening that opens toward the outside of the vehicle. At least a surface of an inner wall of the curved portion on the large diameter side is covered with a water-repellent film and has an uneven shape whose recess portion is R shaped.SELECTED DRAWING: Figure 2

    【課題】燃料電池車両のマフラーから排出される生成水の径の大きさに起因して生じる不具合を抑制可能な技術を提供する。【解決手段】燃料電池が搭載された車両に取り付けられ、該燃料電池から排出される排気ガスおよび生成水を該車両の外部に排出するマフラーであって、マフラーの一部をなし、小径部および該小径部よりも大きな外径の大径部を有する湾曲部であって、車両の外部に向かって開口する開口部を有する湾曲部を備え、湾曲部における少なくとも大径部側の内壁の表面は、撥水膜により覆われ、凹部がR形状である凹凸形状を有する。【選択図】図2
