PROBLEM TO BE SOLVED: To obtain an exhaust structure for a fuel cell vehicle, capable of inhibiting exhaust hydrogen concentration to a predetermined value or less in a simple configuration.SOLUTION: In an exhaust structure 10 for a fuel cell vehicle, a communication hole 28 communicating with an outer space is formed at a throat 24 where an inner diameter of a pipeline is narrowed down. Accordingly, hydrogen discharged into an anode exhaust pipe 16 on an anode side of a fuel cell system 12 is mixed with the air discharged from the fuel cell system 12 through a cathode exhaust pipe 14, and then the hydrogen is mixed with the ambient air introduced from an outer space through the communication hole 28 at the throat 24 of a Venturi tube 18. As a result, hydrogen concentration in exhaust gas is reduced to a predetermined value or less.SELECTED DRAWING: Figure 1

    【課題】簡単な構成で排出水素濃度を所定値以下に抑制できる燃料電池車両用排気構造を得る。【解決手段】燃料電池車両用排気構造10では、管路の内径が絞られたスロート部24に外部空間と連通する連通孔28が形成されている。したがって、燃料電池システム12のアノード側のアノード排気管16に排出された水素は、カソード排気管14で燃料電池システム12から排出された空気と混合された後、ベンチュリ管18のスロート部24で連通孔28を介して外部空間から導入された大気と混合される。この結果、排気中の水素濃度が所定値以下に低減される。【選択図】図1
