The present invention relates to an exhaust pipe structure for a fuel cell vehicle. The exhaust pipe structure for a fuel cell vehicle comprises: a re-circulation flow passage which is mounted in an upper portion of an exhaust pipe in parallel with the exhaust pipe; and a mixing pipe which is mounted in an end portion of the exhaust pipe and through which external air is drawn. When a concentration of hydrogen being discharged is equal to or higher than a reference value, hydrogen is re-circulated into the exhaust pipe via the recirculation flow passage, is mixed with external air via the mixing pipe, and is discharged to the outside. Accordingly, during starting and a hydrogen purge operation of eliminating hydrogen from a fuel cell, high-concentration hydrogen discharged from the fuel cell is discharged out of a vehicle in a state in which a concentration of the hydrogen has been reduced via the recirculation flow passage and the mixing pipe.
본 발명은 연료전지 차량의 배기구 구조에 관한 것으로, 배기파이프와 수평하도록 배기파이프 상부에 장착된 재순환 유체 통로 및, 배기파이프 단부에 장착되고, 외부공기가 흡입되는 혼합파이프를 포함하며, 배출되는 수소의 농도가 기준치 이상일 때, 재순환 유체 통로를 통해 수소를 배기파이프 내부로 재순환 시키고, 혼합파이프를 통해서 외부공기와 혼합하여 외부로 배출함으로써, 시동 및 연료전지에서 수소를 제거하는 수소 퍼지 시, 연료전지에서 배출되는 고 농도의 수소가 재순환 유체 통로 및 혼합파이프를 통해 농도가 저감된 상태로 차량 외부로 배출되는
