Abstract

The invention provides a system for reducing the concentration of tail exhaust hydrogen of a fuel cell system. In the system, the output end of an air compressor is connected with the input end of an intercooler, and the output end of the intercooler is connected with the input end of an electronic three-way valve; the first output end and the second output end of the electronic three-way valve are connected with the first input end of a humidifier and the input end of a back pressure valve respectively; the first output end of the humidifier is connected with the input end of a first throttle valve, the output end of the first throttle valve is connected with the input end of an electric pile, and the first output end of the electric pile is connected with the input end of a second throttle valve. The second output end of the electric pile is connected with the input end of a gas-water separator, the output end of the second throttle valve is connected with the second input end of the humidifier, the second output end of the humidifier is connected with the input end of the back pressure valve, and the output end of the back pressure valve and the output end of the gas-water separator are both connected with a silencer. The invention has the effects that the concentration of tail exhaust hydrogen in the fuel cell system is effectively reduced, and the safety of the hydrogen energy automobile is improved.

Description

technical field [0001] The invention relates to the field of hydrogen energy vehicles, in particular to a system for reducing the concentration of hydrogen gas at the tail of a fuel cell system. Background technique [0002] In the fuel cell system, the safety issue of hydrogen concentration in the exhaust has been widely concerned. The current solution is to use a water-gas separator to separate the water and gas from the anode discharge. Due to the need for drainage, some hydrogen will be discharged with the drainage. Once the tail hydrogen concentration exceeds the standard, there is no effective solution, and there are potential safety hazards. Contents of the invention [0003] In order to solve the above problems, the present invention provides a system for reducing the concentration of hydrogen in the tail gas of a fuel cell system, the system includes an air filter, a flow meter, an air compressor, an intercooler, an electronic three-way valve, and a humidifier , ...
