摘要
文章以质子交换膜燃料电池(Proton Exchange Membrane Fuel Cell,PEMFC)系统为研究对象,分析系统中各组成部件的工作机理,在MATLAB/Simulink软件中搭建了燃料电池电堆电压、阴极、质子交换膜、阳极以及温度的数学机理模型,同时使用Simulink/Simscape物理建模平台搭建热管理系统的物理模型,将两种模型集成为完整的PEMFC系统仿真模型。在所搭建的热管理系统模型中注入典型故障:散热器风扇故障和冷却液流量不足故障,对各故障模式下的燃料电池性能进行了分析。仿真结果表明:PEMFC系统模型结果与试验结果基本一致,验证了模型的合理性;通过对热管理系统故障进行仿真,可以清楚地了解故障发生的机理,为其故障诊断提供了参考依据。
This paper analyzes the working mechanism of each components of the proton exchange membrane fuel cell(PEMFC)system,and the mathematical mechanism models of stack,anode,cathode,proton exchange membrane,and temperature of the PEMFC are established using MATLAB/Simulink software,furthermore,the physical model of thermal management system is built in the Simulink/Simscape environment,and the mathematical and physical models are integrated into a complete PEMFC system simulation model.Typical malfunctions,including the radiator fan failure and insufficient coolant flow failure,are injected into the PEMFC system simulation model to analyze the influence of malfunctions on the performance of PEMFC.The simulation results are basically consistent with the experimental results,which indicates that the proposed model is reasonable and accurate.Moreover,the generation mechanism of malfunctions is figured out through malfunction simulation of the thermal management system,which provides a reference for malfunction diagnosis.
