摘要
从热力学和动力学理论出发,对燃料电池的工作原理进行研究。通过对活化极化、浓差极化、欧姆极化的数学描述,建立电化学仿真模型。结合试验数据,辨识模型中的参数,并用MATLAB/SIMULINK仿真平台对质子交换膜燃料电池进行仿真分析。结果表明:仿真结果与实验数据比较吻合,模型具有良好的稳态性能,能够有效应用于燃料电池系统理论和技术研究。
The operating principle of PEMFC is studied according to the theory of thermodynamics and dynamics. An electrochemical simulation model is set up by describing activation polarization, concentration polarization and ohmic polarization. The model parameters are determined with experimental data, and the model is analyzed on the platform of MATLAB/SIMULINK. The results show that the simulation results are in agreement with the experimental data, the model has good steady-state behavior and can be applied to the research of theory and technology of proton exchange membrane fuel cell systems.
