摘　　要：为研究质子交换膜燃料电池(PEMFC)的输出特性,在目前已提出的动态模型基础上进行了改进,并加入气体流量模型和热力学模型,利用Matlab-Simulink仿真工具,建立了一种新颖的PEMFC系统动态模型。仿真结果表明该模型较好地反映出PEMFC系统的动态特性,有助于进一步完善PEMFC系统模型,为改进PEMFC输出性能和设计实时控制系统,提供了可靠依据。In order to investigate the output characteristic of proton exchange membrane fuel cell （PEMFC）, a novel dynamic model of PEMFC was developed including gas flow model and thermodynamics model based on previous model by using Matlab-Simulink. The eomprehensive results of simulation manifest that the model can refleet the dynamic characteristic of PEMFC system. It is useful to improve the dynamic model of PEMFC system, the output performance of PEMFC and is applicable to design the control system of PEMFC.
