基于对称蛇形流场的PEMFC双极板流道尺寸优化
Optimization design of PEMFC bipolar plate channel dimensions based on symmetric serpentine flow field
摘要
Abstract
Based on the symmetric serpentine flow field bipolar plate,the design method of central composite experiments was adopted,with the bipolar plate flow channel structural parameters as the optimization variables,and the maximum power density of the PEMFC and the differential pressure between the inlet and outlet of the bipolar plate flow channel as the objectives.The internal flow char-acteristics and electrochemical properties of PEMFC based on the optimal symmetric serpentine flow field dimensions were investigated by means of experimental design and numerical simulation,and compared with the unoptimized flow field.The optimization design results show that the greatest in-fluence factors on the maximum power density and the differential pressure are the linear flow chan-nel width and depth of the bipolar plate flow field,respectively.When the auxiliary flow channel width is 1 mm and the ridge width is 1.4 mm,the optimal range of linear runner width is 1.14-1.68 mm and the optimal range of flow channel depth is 0.9-1.51 mm.Under the same conditions,the maximum power density of the symmetric serpentine flow field PEMFC with the optimized bipolar plate flow channel is 0.662 W/cm2,which is 10%higher than that(0.601 W/cm2)of the unoptimized flow channel.关键词
