- Abstract
How to shorten the PEMFC development cycle is one of the key concerns of the PEMFC industry at present. Among them, developing a high-precision and high-efficiency PEMFC performance analysis platform is an important method to accelerate the PEMFC development progress. In this paper, from the PEMFC reaction mechanism and engineering development experience, we firstly analyze the mechanism and mathematical modeling of PEMFC reactor, and establish the voltage sub-model, cathode runner sub-model, anode runner sub-model and membrane hydration sub-model. Then, the performance analysis of the core components of the cathode system, such as air compressor, intercooler, humidifier and backpressure valve, was carried out, and a sub-model of each component was established. Further, the mathematical model of the anode system including the hydrogen circulation pump and the pressure regulating valve is studied and established. In addition, the core components of radiator, cooling water pump and thermostat are analyzed mechanically, and the PEMFC hydrothermal management system model is established. Finally, the established PEMFC model was experimentally verified. The results show that the constructed mathematical model for PEMFC performance analysis can accurately simulate the PEMFC working process and output reasonable numerical results with the error within 5%.
