Development and experimental of high⁃power proton exchange membrane fuel cell test system

In view of the current high-power fuel cell system, a high-power fuel cell test platform was designed and developed, and the performance test of the 120 kW fuel cell was completed through the design, selection, construction, and debugging of the system. The test platform integrates hydrogen flow，air flow and thermal management control systems, integrates and optimizes the layout between the various subsystems, and makes post-maintenance more convenient. At the same time, the test platform uses LABVIEW software to design the control interface of the upper computer, uses Simulink software to design the control program of the lower computer controller and writes the determined parameters of the components into the controller, and then realizes the communication through the CAN box between the upper computer and the controller. The online real-time control of the system by the host computer control interface, and can automatically optimize the operating parameters of each component according to the load change. By analyzing the test data collected by the test platform, it is possible to evaluate whether the fuel cell system meets the expected design requirements. The test platform has certain guiding significance for the research and production of high-power fuel cell systems and the development of fuel cell test platforms, and provides a guarantee for the development of fuel cell systems. © 2022 Editorial Board of Jilin University.
