The invention discloses a proton exchange membrane fuel cell dynamic performance testing system, which includes a hydrogen cylinder, a filter, a three-way valve, a flow control valve, a stop valve, a temperature sensor, a humidity sensor, a pressure sensor, a flow sensor, and a spraying device. Proton exchange membrane fuel cell stack, air compressor, pressure reducing valve, PC controller and display device. The invention also discloses a working method of a proton exchange membrane fuel cell testing system, which controls a single parameter of the intake gas of the proton exchange membrane fuel cell while keeping other parameters unchanged. Conduct multiple tests to explore the optimal parameters of the fuel cell; at the same time, the water circulation heat dissipation system is designed for the waste heat generated by the proton exchange membrane fuel cell during the reaction, and makes full use of the heat energy in the circulating water, which not only improves efficiency but also reduces energy loss , The proton exchange membrane fuel cell reaction only produces water and will not pollute the environment.
Description
technical field [0001] The invention belongs to the field of fuel cell testing, and in particular relates to a proton exchange membrane fuel cell dynamic performance testing system and a working method thereof. Background technique [0002] A fuel cell is a device that directly converts the chemical energy of a fuel into electrical energy. It only takes place in an electrochemical reaction and does not have a combustion process, so it is not limited by the Carnot cycle. It has extremely high energy conversion efficiency. [0003] Fuel cells can ideally be all-solid-state mechanical structures, ie, have no moving parts, and such systems would potentially have high reliability and long life. And when the fuel cell uses hydrogen and oxygen as fuel to generate water, there is no pollution and can be recycled, which is more friendly to the environment. [0004] Due to the advantages of high efficiency, no pollution, long life and high reliability, fuel cells can be used as a sub...
