PROBLEM TO BE SOLVED: To atomize generated water while maintaining ventilation resistance of an exhaust pipe small.SOLUTION: In an exhaust pipe structure 10, a turbulent flow is generated in used air flowing through a channel 30A of a turbulent flow generation part 30 by a blade 36 of a turbulent flow generation part 30 provided in the vicinity of an exhaust port 14A in a cathode exhaust pipe 14. Thus, generated water discharged from the exhaust port 14A to the outside of a vehicle is atomized by the turbulent flow. The generated water is atomized by the turbulent flow generated by the blade 36 such that it is possible to make a ventilation cross-sectional area larger than a structure (comparison example) in which the generated water is crushed and atomized by increasing a flow rate at a venturi part. Therefore, it is possible to make the ventilation cross-sectional area larger than the comparison example in the exhaust pipe structure 10. Thus, it is possible to atomize the generated water while maintaining ventilation resistance of the cathode exhaust pipe 14 smaller than the comparison example.SELECTED DRAWING: Figure 2

    【課題】排気管の通気抵抗を小さく維持しつつ、生成水を霧化できるようにする。【解決手段】排気管構造10では、カソード排気管14の内部において排出口14Aの近傍に設けられた乱流発生部30のブレード36によって、乱流発生部30の流路30Aを流通する使用済み空気に乱流を生じさせる。これにより、排出口14Aから車外へ放出される生成水を当該乱流により霧化する。このように、生成水をブレード36による乱流によって霧化するので、ベンチュリ部での高流速化によって生成水を破砕して霧化する構造(比較例)に比べ、通気断面積を大きくできる。よって、排気管構造10では、比較例に比べ、通気断面積を大きくできるので、比較例に比べてカソード排気管14の通気抵抗を小さく維持しつつ、生成水を霧化できる。【選択図】図2
