Problems solved by technology

Similarly, during the hydrogen cycle, the impurities in the fuel hydrogen, the N2 in the cathode air and the water produced by the reaction will accumulate on the anode through the proton exchange membrane. After a long time of operation, the partial pressure of hydrogen will decrease, and the resulting liquid Water will hinder the contact of hydrogen gas with the catalyst layer, causing the battery stack voltag

The system comprises a high-pressure hydrogen bottle, a pressure reducing valve, a first switch valve, a gas storage tank, a first pressure regulating valve, a first three-way valve, a proportional valve, a second three-way valve, a hydrogen discharging valve and a second switch valve, wherein the pressure reducing valve is connected with the high-pressure hydrogen bottle and the first switch valve, a to-be-tested hydrogen supply circulating device is connected between the first switch valve and the gas storage tank, the first pressure regulating valve is connected with the gas storage tank and the first three-way valve, one end of the first three-way valve is connected with the proportional valve, the other end of the first three-way valve is connected with the second three-way valve, and a to-be-testedhydrogen return device is connected between the other end of the second three-way valve and the to-be-tested hydrogen supply circulating device. The system is advantaged in that the rapid response capability of the hydrogen supply circulating device of the fuel cell can be effectively tested, and the performance test of the hydrogen supply circulating device and optimization of a controller purging strategy are facilitated.

Description

technical field [0001] The invention relates to the technical field of hydrogen fuel cells, in particular to a test system for the rapid response capability of a fuel cell hydrogen supply cycle device. Background technique [0002] In order to improve the utilization rate of hydrogen, reduce the cost of fuel cell power generation, and obtain higher stack performance, a closed-end operation is often performed on the anode hydrogen of the stack. A common hydrogen closed-end technology for fuel cells is the hydrogen cycle mode. [0003] The method of hydrogen circulation can ensure the efficient and stable operation of the fuel cell, and can also discharge the water generated in the fuel cell to the outside of the battery, that is, after the hydrogen gas takes out the water generated inside the stack, the liquid water and hydrogen gas are separated by the gas-water separation device. Separate, and then send the hydrogen cycle back to the anode of the stack for reuse, and at th...
