2.5kW质子交换膜燃料电池系统建模、仿真及其优化研究

Modelling, Simulation and Optimisation of a 2,5 kW PEM Fuel Cell System

本文介绍了2.5kW质子交换膜燃料电池(PEM Fuel Cell——PEMFC)系统的建模、仿真及其优化等研究工作,包括燃料电池堆的动态仿真模型建模过程、湿度和温度控制电路的设计过程。对湿度控制电路的新型模型参考控制策略的建模、仿真及应用表明,该控制策略能够显著提高系统供电质量,以及保证系统长时期运行的稳定性。

This paper presents the results of the experimentalinvestigations, simulation and optimisation of a 2,5kWPEM-Fuel-Cell （PEMFC） system. A dynamic simulationmodel for the fuel cell stack, the humidity, and thetemperature control circuits was developed. A newmodel reference control strategy for the humidity controlcircuit was modelled, simulated and applied, leadingto a significant improvement of power quality andlong term system stability.
