상기 공기공급유로(54)에는 상기 공기공급장치(50)에서 상기 희석장치(56)로 공급되는 공기를 단속하는 조절밸브(58)가 설치된다.The air supply passage 54 is provided with a control valve 58 to control the air supplied from the air supply device 50 to the dilution device 56.

상기 통기관(62)과 희석장치(56)는 관 형상으로 형성된다.The vent pipe 62 and the dilution device 56 are formed in a tubular shape.

특히, 상기 통기관(62)은 상기 배기통로(52)에 입구와 출구가 연결되고, 상기 희석장치(56) 내부에 일정간격 이격되게 설치된다.In particular, the inlet pipe 62 is connected to the inlet and the outlet to the exhaust passage 52, it is installed in the dilution device 56 spaced apart a predetermined interval.

이때, 상기 통기관(62)은 연료전지에서 배기되는 배기가스와 상기 공기공급장치(50)에서 공급되는 공기가 둘 다 통과할 수 있도록 상기 배기통로(52)보다 단면적이 넓게 형성된다. 즉, 상기 통기관(62)의 단면적은 상기 배기통로(52)보다 넓고, 상기 희석장치(56)보다는 좁게 형성된다.At this time, the exhaust pipe 62 has a larger cross-sectional area than the exhaust passage 52 so that both the exhaust gas exhausted from the fuel cell and the air supplied from the air supply device 50 can pass therethrough.
