EXHAUST SYSTEM FOR AIR-COOLED FUEL CELL VEHICLE

摘要

Disclosed is an air-cooled fuel cell vehicle which is provided with an air-cooled fuel cell stack supplied with air that acts as a reaction gas and a cooling medium, which improves exhaust performance of an exhaust duct for discharging excess air and hydrogen gas from the air-cooled fuel cell stack, and which prevents the infiltration of water and foreign matter into the air-cooled fuel cell stack. In the exhaust device for an air-cooled fuel cell vehicle, an exhaust duct, which conveys the hydrogen and air discharged without being consumed in the air-cooled fuel cell stack to outside the vehicle, is configured from a vertically-branching lower exhaust duct and upper exhaust duct. The lower exhaust duct extends towards the bottom of the vehicle from the exhaust outlet of the air-cooled fuel cell stack so that the downstream end of the lower exhaust duct opens below the front cabin, and the upper exhaust duct extends towards the top of the vehicle from the top of the outer wall of the lower exhaust duct extending towards the bottom of the vehicle so that the downstream end of the upper exhaust duct opens between the rear of the front hood and the front of the front window.
