智能电网中PEMFC分布式电源的建模及性能分析

Modeling and performance analysis of proton exchange membrane fuel cell based distributed power source in smart grid system

采用风能、太阳能、燃料电池等清洁能源发电的分布式电源是智能电网的重要组成部分。质子交换膜燃料电池PEMFC作为分布式发电的一种,具有能量密度高,环境污染小,噪音低,启动快,工作温度低等优点。文中建立了PEMFC燃料电池的数学模型,采用Simulink软件搭建了仿真模型,并对PEMFC燃料电池在不同温度及气体压力下的发电效率进行了分析。

The distributed power generation uses the wind, sunshine and fuel cell to produce power, and it is an important composition of smart grid. Proton exchange membrane fuel cell（PEMFC） is one way of the distributed power generation, it has a lot of advantages of less environmental pollution, low noise, fast starting and low operating temperature. A mathematical model of a PEMFC has been built, after building a simulation model by the Simulink, the analysis on the performance of PEMFC working at different temperature and at gas different pressure was carried out.
