Abstract

The invention relates to a fuel cell hydrogen tail gas recycling system. The fuel cell hydrogen tail gas recycling system includes a fuel cell hydrogen supply system, a hydrogen recovery mechanism and a controller: the fuel cell hydrogen supply system includes a fuel cell stack, a hydrogen intake pipe connected to the intake end of the fuel cell stack, and The exhaust pipe connected to the exhaust end of the fuel cell stack; the hydrogen recovery mechanism includes a gas-water separation mechanism connected to the exhaust pipe, a hydrogen buffer mechanism connected to the gas-water separation mechanism, and a gas recovery mechanism connected to the hydrogen buffer mechanism. The pipeline and the gas recovery pipeline are used to connect with the hydrogen inlet pipe or the external gas storage container; the controller is connected with the gas-water separation mechanism and the hydrogen buffer mechanism. The invention can recycle the hydrogen discharged from tail gas, reduce the waste of hydrogen, improve the performance of the fuel cell, and solve the safety threat of the tail hydrogen of the fuel cell stack and the potential harm to the atmospheric environment.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a fuel cell hydrogen tail gas recovery system. Background technique [0002] Fuel cell vehicles are the third stage of the development of new energy vehicle technology, which can solve the problems of pure electric vehicles such as mileage anxiety, long charging time, battery pollution, etc., especially in commercial vehicles, and have a good application prospect. During the operation of the fuel cell stack, in order to ensure the purity of hydrogen and prevent water blockage on the anode side, it is necessary to discharge hydrogen tail gas intermittently, resulting in a waste of hydrogen. At the same time, these tail gases have the following hazards: There is a danger of deflagration; ②It is easy to accumulate in buildings with roofs, especially in underground garages. potential hazard. Contents of the invention [0003] The invention provides a fuel cell hydrogen tail ga...
