PROBLEM TO BE SOLVED: To provide an exhaust port structure for a fuel cell vehicle capable of reducing a hydrogen concentration of an exhaust gas that is exhausted into atmospheric air during initial start and hydrogen purge of the fuel cell vehicle.SOLUTION: The exhaust port structure includes: a re-circulation fluid passage which is fitted in an upper part of an exhaust pipe so as to be in parallel with the exhaust pipe; and a mixing pipe which is fitted in an end of the exhaust pipe and into which external air is sucked. The re-circulation fluid passage is communicated with a suction duct so as to generate a flow of a mixture gas to the re-circulation fluid passage. The mixture gas is re-circulated through the re-circulation fluid passage into the exhaust pipe, and the mixture gas that is re-circulated into the exhaust pipe is mixed with external air via the mixture pipe and exhausted to the outside. If a hydrogen concentration of the mixture gas being present in a connection portion of the exhaust pipe and the re-circulation fluid passage is higher than a hydrogen concentration of the mixture gas that flows into the exhaust pipe, the re-circulation fluid passage and the suction duct are communicated.SELECTED DRAWING: Figure 1

    【課題】燃料電池車両の初期始動及び水素パージの際に大気に排出される排出ガスの水素濃度を低減することができる燃料電池車両の排気口構造を提供する。【解決手段】本発明は、排気パイプと水平をなすよう、排気パイプの上部に取り付けられた再循環流体通路、及び排気パイプの端部に取り付けられ、外部空気が吸入される混合パイプを含み、前記再循環流体通路への混合ガスの流動が生成されるよう、前記再循環流体通路が吸気ダクトと連通され、前記再循環流体通路を介して混合ガスが前記排気パイプの内部に再循環され、前記排気パイプの内部に再循環された混合ガスは、前記混合パイプを介して外部空気と混合され外部へ排出されることを特徴とし、前記排気パイプに流入される混合ガスの水素濃度より、前記排気パイプと前記再循環流体通路の連結部位に存在する混合ガスの水素濃度が高い場合、前記再循環流体通路と前記吸気ダクトが連通されることを特徴とする。【選択図】図1
