基于蜂窝仿生流场的质子交换膜燃料电池的性能研究及优化OA北大核心CSTPCD
Performance optimization of proton exchange membrane fuel cell based on honeycomb-like flow field
为了增强质子交换膜燃料电池(PEMFCs)内部燃料分布的均匀性与水管理能力,本文研究了一种新型的基于仿生结构的蜂窝仿生流场.首先,根据蜂窝结构特征,搭建出三维多相流非等温几何模型并确立PEMFC的数学模型;其次,采用计算流体动力学Fluent软件对模型进行无关性与有效性验证,并对蜂窝仿生流场和常规平行流场的电池性能和燃料分布进行了模拟分析;最后,对比极化性能、气体流速分布、燃料与液态水组分浓度和电流密度分布,验证了蜂窝仿生流场设计的有效性.研究结…查看全部>>
In order to enhance the uniformity of fuel distribution and capability of liquid water management in the proton exchange membrane fuel cells(PEMFCs),a novel honeycomb-like flow field based on bionic structure was proposed.Firstly,a three-dimensional multiphase flow non-isothermal geometric model was constructed based on the honeycomb structural features,and the mathematical model of PEMFCs was established.Secondly,the model was verified for irrelevance and v…查看全部>>
