PROBLEM TO BE SOLVED: To provide a hydrogen detector of a fuel cell vehicle which reliably detects hydrogen concentration in an exhaust duct and secures life of a hydrogen concentration detector.SOLUTION: A hydrogen detector 69 of a fuel cell two-wheeled vehicle 1 includes: a vehicle body 5; an air-cooling fuel cell 2 which is mounted on the vehicle body 5 and causes a hydrogen gas to react with oxygen in air to generate power; an exhaust duct 52 which guides exhaust air of the fuel cell 2 to a rear end part of the vehicle body 5 to exhaust air to the outside of the vehicle; and a hydrogen concentration detector 71 which is disposed at an outer side of the exhaust duct 52 and detects hydrogen concentration. The exhaust duct 52 has a detection hole 103 which penetrates through a ceiling wall 102 and allows a gas in the exhaust duct 52 to flow therefrom. The hydrogen concentration detector 71 detects hydrogen concentration of the gas flowing to the outside of the exhaust duct 52 through the detection hole 103.SELECTED DRAWING: Figure 4

    【課題】排気ダクト内の水素濃度の確実な検出と、水素濃度検出器の寿命の確保とを両立可能な燃料電池車両の水素検出装置を提案する。【解決手段】燃料電池二輪車1の水素検出装置69は、車体5と、車体5に搭載され、水素ガスと空気中の酸素とを反応させて発電する空冷式の燃料電池2と、燃料電池2の排気を車体5の後端部に導いて車外へ排気する排気ダクト52と、排気ダクト52の外側に配置され、水素の濃度を検出する水素濃度検出器71と、を備えている。排気ダクト52は、天井壁102を貫通し、排気ダクト52内の気体を流出させる検出孔103を有し、水素濃度検出器71は、検出孔103を通じて排気ダクト52外に流出する気体の水素濃度を検出する。【選択図】 図4
