质子交换膜燃料电池温度控制仿真模型

Simulation Model of PEMFC Temperature Control

通过对质子交换膜燃料电池电化学反应的热力学特性分析计算,建立了质子交换膜燃料电池的热力系统动态数学模型,并且在 Matlab/Simulink 平台上建立了温度控制仿真模型。从实用的角度,结合燃料电池发动机研发工作,提出了一套不需要精确的系统内部特性和结构参数的燃料电池温度控制仿真模型建模方法。

Based on the analyzing of thermodynamic feature of proton exchange membrane fuel cell electrochemical performance as well as its structure, a thermal system control simulation model is introduced. This model includes the whole PEMFC engine system, not only a single cell or a fuel cell stack, and appropriate equations are presented to consider the varying of thermodynamic energy. The model is tested by using Matlab/simulink software. Cooperated with practical FCE research working a feasible modeling method is offered, which needs only the parameters that can be easily measured, such as temperature, humidity and flux.
