摘　　要：分析了质子交换膜燃料电池(Proton Exchange Membrane Fuel Cell,PEMFC)冷启动过程,在集总参数经验模型的基础上,选取恰当的数学原型对其改进,提出一种新的PEMFC冷启动过程电气特性动态模型以及一种用以描述单池滞后时长与电池特定参数之间关系的定性函数,指出了造成PEMFC系统是滞后系统的原因;利用MATLAB/Simulink对所提出的模型进行仿真;结合实验验证结果,提出一种用以解释实验中出现单池"反极"现象的新观点。The cold-start process of proton exchange membrane fuel cell （PEMFC） was analyzed and an original mathematical model, based on the lump-parameter empirical model, was determined and modified properly for a new electrical characteristic dynamic model of cold-start of PEMFC system; a qualitative function was presented to describe the relationship between single cell delay-time length and the PEMFC specific parameters, from which the reason for explaining why PEMFC system has a time-delay electrical characteristic was provided; MATLAB/ Simulink was applied to establishing the proposed model; a new view point, through the result of verify experiment, was put forward for revealing the essence of the ＂inverse polarity＂ phenomenon on some cells.
