Abstract

The invention provides a fuel cell system air path control system and method. The fuel cell system air path control system comprises an air compressor, a humidifier, a valve R1, a valve R2, a three-way valve T1 and a valve R3. The air compressor is respectively connected with the valve R1 and a first inlet of the humidifier through pipelines, the valve R2 is arranged between a first outlet of thehumidifier and an air inlet of the fuel cell, an air outlet of the fuel cell is sequentially connected with the three-way valve T1 and the valve R3 through pipelines, and the valve R3 and the valve R1are jointly connected to an exhaust port. Parameters of air entering the fuel cell are monitored in real time through the related sensors, the effect of controlling the parameters of the air inlet ofthe fuel cell is achieved by adjusting the corresponding electric valves, and more fuel cell system air path control strategies are achieved.

Description

technical field [0001] The invention relates to the technical field of fuel cell systems, in particular to a fuel cell system air circuit control system and method. Background technique [0002] In recent years, the development of fuel cells has attracted more and more attention from the public, among which proton exchange membrane fuel cells are the most widely used. A fuel cell is a device that generates water and electrons through the reaction of hydrogen and oxygen in the air. However, the pressure, temperature, flow, and humidity of the gas will directly affect the performance of the fuel cell. The generation of water is mainly in the air path of the fuel cell. At present, the water brought out by the air outlet is generally used to humidify the air entering the fuel cell through a humidifier. [0003] Normally, there is only one main air path in the fuel cell system, and there is no bypass to match the diversion of air. At this time, the air path is completely control...
