Abstract

The invention provides a hydrogen energy automobile fuel cell system, and relates to the technical field of fuel cell systems. The fuel cell system comprises an electric pile, an air compressor, a pile outlet throttle valve, a hydrogen cylinder, a voltage inspection module and a controller. An air inlet, an air outlet, a hydrogen inlet, a hydrogen outlet, a hydrogen discharging valve and a water discharging valve are arranged on the galvanic pile; the pile outlet throttle valve is communicated with the air outlet; the air compressor is communicated with the galvanic pile through the air inlet;an in-pile throttle valve is arranged between the air compressor and the air inlet; the hydrogen cylinder is communicated with the galvanic pile through the hydrogen inlet; an in-pile hydrogen valveis arranged between the hydrogen cylinder and the hydrogen inlet; the in-pile hydrogen valve is respectively communicated with the hydrogen cylinder and the hydrogen inlet; the controller is electrically connected with the air compressor, the pipe inlet throttle valve, the pipe outlet throttle valve, the in-pile hydrogen valve and the voltage inspection module. The invention further provides a control method of the hydrogen energy automobile fuel cell system. And attenuation of the performance of the galvanic pile can be effectively slowed down.

Description

technical field [0001] The invention relates to the technical field of fuel cell systems, in particular to a hydrogen vehicle fuel cell system and a control method thereof. Background technique [0002] Compared with the currently widely used electric energy supply system, hydrogen energy, as an energy storage material in the transportation industry, has the characteristics and advantages of large-scale stable storage, continuous supply, long-distance transportation, and rapid replenishment. In the energy structure characterized by primary and zero emissions, there will be a hydrogen energy system that coexists and complements the power system to jointly meet the energy needs of transportation, family life, and industrial production. [0003] A fuel cell is an energy conversion device that converts the chemical energy of hydrogen and air (oxygen) into electrical energy through an electrochemical reaction. Since there is no high-temperature combustion process, the only emiss...
