Abstract
The invention discloses an air exhaust system. The air exhaust system comprises an exhaust fan and a gas collector with an air inlet and an air outlet, and a gas inlet of the exhaust fan is communicated with the air outlet of the gas collector through a pipeline. When the air exhaust system is applied, the gas collector is disposed at the inner top of a trunk of a fuel cell vehicle, the air outlet of the gas collector is connected with the gas inlet of the exhaust fan, and when the exhaust fan is turned on, air inside the trunk enters the gas collector and enters the exhaust fan through the pipeline so as to be exhausted to the atmosphere. By the process, hydrogen gas existing in the air inside the trunk can be exhausted through the gas collector and the exhaust fan to enable the air inside the trunk to be changed continuously, so that too high concentration of the hydrogen gas around a hydrogen gas cylinder can be prevented effectively. The invention further discloses the fuel cell vehicle with the air exhaust system.
