小型船用PEM燃料电池仿真特性分析

Simulation analysis of PEM fuel cell for small boat

随着能源的逐渐枯竭和环境污染的持续加重,燃料电池的发展越来越受到世界各国的重视,燃料电池具有高效、清洁和环保等特点,特别是质子交换膜(PEM)燃料电池已经得到了广泛的应用。文章基于Matlab/Simulink软件平台,建立PEM燃料电池动态模型,以输入信号源作为外加负载,分析了随负载电流变化时,电池工作温度变化和阴阳极进气压力对PEM燃料电池输出电压和输出功率的影响。仿真结果与实际燃料电池特性曲线基本一致,所搭建的动态模型也能较好的反映PEM燃料电池的动态特性。

With the gradual depletion of energy and the continuous aggravation of environmental pollution,the development of fuel cells has been paid more and more attention in the world,and fuel cells have the characteristics of high efficiency,cleanliness and environmental protection,especially proton exchange membrane fuel cells have been widely used.Based on the Matlab/Simulink software platform,the dynamic model of proton exchange membrane fuel cell is established,and the effect of the operating temperature of the battery and the inlet pressure of the anode on the output voltage and output power of the proton exchange membrane(PEM)fuel cell is analyzed when the load current changes.Simulation Results and Reality The characteristic curve of international fuel cell is basically consistent,and the dynamic model can also better reflect the dynamic characteristics of PEM fuel cell.
