Abstract

The invention discloses a fuel cell air system, and relates to the technical field of hydrogen fuel cells. The problems of ventilation quantity and water accumulation are solved. The fuel cell air system specifically comprises a fuel cell shell, a fuel cell is arranged in the fuel cell shell, and a gas inlet system and a gas outlet system are arranged at a gas inlet and a gas outlet of the fuel cell shell; the air inlet system comprises an air filter, a flow meter, an air compressor, an intercooler, a humidifier, a dehumidification electromagnetic valve, a ventilation electromagnetic valve, a temperature sensor, a pressure sensor and a humidity sensor, the exhaust system comprises a back pressure valve, a mixer, a bypass electromagnetic valve, a one-way valve and a hydrogen concentration sensor, and the humidifier is connected to an air inlet of the fuel cell shell through a connecting hose; the temperature sensor and the humidity sensor are arranged on the circumference of the connecting hose, and the output end of the intercooler is connected to the input end of the humidifier through the connecting hose. The problem that the local hydrogen concentration is too high due to local hydrogen retention dead angles is solved.

Description

technical field [0001] The invention relates to the technical field of hydrogen fuel cells, in particular to a fuel cell air system. Background technique [0002] The hydrogen fuel cell works by the electric energy generated by the chemical reaction of hydrogen and oxygen. During the reaction process, it is necessary to ensure the supply of air with appropriate pressure and humidity, and at the same time ensure the smooth discharge of exhaust gas. Therefore, it is necessary to reasonably arrange the fuel cell air. It is very important that the system regulates it at the same time. [0003] However, in the traditional fuel cell air system, the ventilation volume of the device cannot be effectively adjusted, a large amount of energy is wasted, and there is a problem of moisture accumulation at the bottom of the device. and humidity can be effectively monitored. Contents of the invention [0004] The object of the present invention is to propose a fuel cell air system in or...
