To provide an exhaust system for a fuel cell vehicle that can reliably prevent a fuel cell from being immersed with water, and to provide a fuel cell system.SOLUTION: An exhaust system 100 for a fuel cell vehicle includes a muffler 1 installed downstream of an exhaust gas passage 2 of a fuel cell 10. The exhaust system 100 includes: a first shut-off valve 3 installed between the fuel cell 10 and the muffler 1; a water level sensor 5 included in the muffler 1 to detect a level of water immersed into the muffler 1; and a control unit 6 configured to control the first shut-off valve 3 to open and close and control the first shut-off valve to close when a water level detected by the water level sensor exceeds a first threshold. The control unit 6 changes the first threshold Hf in accordance with a rise degree of the detected water level.SELECTED DRAWING: Figure 2

    【課題】燃料電池の浸水を確実に防止できる燃料電池車両の排気装置及び燃料電池システムを提供する。【解決手段】燃料電池10の排ガス流路2下流に設けられるマフラー1を備えた燃料電池車両の排気装置100が提供される。この排気装置100は、燃料電池10とマフラー1との間に設けられる第1遮断弁3と、マフラー1内に備えられ、マフラー1内に浸入した水の水位を検知する水位センサ5と、第1遮断弁3の開閉を制御するよう構成され、水位センサにより検知された水位が第1の閾値を超えると、第1遮断弁を閉弁する制御部6を備える。制御部6は、検知された水位の上昇度合いに応じて第1の閾値Hfを変更する。【選択図】図2
