Research on Thermal Management System of Advanced Proton Exchange Membrane Fuel Cells in Fuel Cells

Abstract

This paper takes proton exchange membrane fuel cell system as the research object. The working mechanism of each component in the system is also studied. A mathematical model of dynamic thermal management of reactor based on the theory of functional conservation is proposed. This project proposes an optimal quadratic programming algorithm based on Lyapunov function, and solves it with iterative algorithm. By using MATLAB/Simulink simulation analysis method, the calculation model of reactor voltage, cathode, proton exchange membrane, anode temperature and other parameters is established. Simulink/Simscape modeling software was used to simulate it. These two models are integrated to form a comprehensive battery simulation model. The operating characteristics of the fuel cell were studied under various failure modes. The simulation results of PEMFC are in agreement with the experimental results. The results show that the method is reasonable. Through the simulation of its failure process, people can understand its failure mechanism more clearly. The research results of this paper have certain guiding significance for the fault diagnosis of the motor.
