| 摘 要： | 为了获得较优的流道深度、流道宽度和流道岸的宽度,采用计算流体动力学软件Fluent的PEM模块进行数值模拟和优化设计.研究表明,直流道流场的深度为0.4 mm时,电池性能最好,流道岸的宽度不要超过流道宽度,较优的流道宽度和流道岸的宽度比值为1:1和2:1.

| Abstract: | In order to obtain the optimal channel depth,width of the flow field and width of the shoulder,the flow fields in a PEM(proton exchange membrane) fuel cell are modeled and optimized by using a CFD software Fluent and its PEM module.The results show that the fuel cell performance is the best when the channel depth of the flow field with straight channels is 0.4mm,and the width of the shoulder must not exceed width of the flow field channel,and the optimal ratio of the width over the shoulder of the flow fiel... |
