Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a test device for a fuel cell air supply system and a control method thereof. Background technique [0002] A proton exchange membrane fuel cell is a device that converts the chemical energy of fuel (hydrogen) and oxidant (air) into electrical energy. Since the fuel cell converts the Gibbs free energy in the chemical energy of the fuel into electrical energy through an electrochemical reaction, it is not limited by the Carnot cycle effect, and the additional product is only water, so the fuel cell has high energy conversion efficiency and environmental protection. Friendly and so on. [0003] In the fuel cell system, air is provided by the air supply system as an oxidant to complete the electrochemical reaction. Among them, the air compressor is one of the main components of the fuel cell air supply system, which plays the role of compressing air and pumping it into the stac...

Problems solved by technology

[0004] However, the cooling parameters in the current fuel cell air supply system are relatively fixed, for example, for different air compressors, the cooling circuit parameter settings may be completely the same

If the cooling efficiency is insufficient, the temperature of the air entering the stack may be too high, which will affect the performance and life of the fuel cell. If the cooling efficiency is too high, it will cause a waste of cooling resources
