摘要

在ANSYS/Fluent软件中建立全尺度的小型空冷型质子交换膜燃料电池（PEMFC）堆仿真模型

并采用计算流体力学（CFD）方法进行求解。研究不同海拔高度和阴极过量系数对电池堆的输出性能、温度和氧气浓度的影响。结果表明：海拔升高到3200 m时

电池堆的峰值功率密度降低了21.6%;增加阴极过量系数可补偿因海拔升高而降低的氧气浓度

提高电池堆的输出性能

减小电池堆的内部温度差异。

Abstract

A full-scale simulation model of a small air-cooled PEMFC stack is established in ANSYS/Fluent software

and the solution is obtained using computational fluid dynamics （CFD） methods. The effects of different altitudes and cathode stoichiometric ratios on the output performance

temperature

and oxygen concentration of the fuel cell stack are investigated. The results indicate that when the altitude increases to 3200 m

the peak power density of the fuel cell stack decreases by 21.6%. Increasing the cathode stoichiometric ratio can compensate for the decrease in oxygen concentration caused by higher altitudes

improve the output performance of the fuel cell stack and reduce the internal temperature differences within the stack.
