摘要

质子交换膜燃料电池(PEMFC)是一种便携式清洁能源发电设备。流场的结构排列对PEMFC的输送效率有显著影响。本文以蜘蛛的形状为灵感，设计了一种新的仿生流道。以支路宽度和支路转角为研究重点，采用计算流体力学(CFD)方法进行了数值模拟。结果表明，当通道宽度/肋宽和支路转角分别为1.5°和130°时，是最佳数值组合，小区综合性能优异。最后将该数值组合模型与传统流道模型进行了比较，验证了该方案的先进性。

Design and Analysis of Spider Bionic Flow Field for Proton Exchange Membrane Fuel Cell

Proton exchange membrane fuel cell (PEMFC) is a portable and clean power generation device. The structural arrangement of the flow field has a significant influence on the delivery efficiency of PEMFC. In this article, a new bionic flow channel is designed based on the inspiration of a spider shape. The branch channel width and branch corner are studied as the focus, and its simulation is carried out by the method of computational fluid dynamics (CFD). The results show that when channel width/rib width and corner of the branch are 1.5 and 130 o , respectively, it is the best numerical combination and the cell comprehensive performance is excellent. The final model using this numerical combination is compared with the traditional flow channel model to verify the advancement of this scheme.
