摘　　要：车用燃料电池在怠速工况下的运行性能是制约其商业化的技术挑战之一。运用基于商用计算流体动力学(Computational Fluid Dynamics,CFD)软件Fluent及其质子交换膜燃料电池(Proton Exchange Membrane Fuel Cell,PEMFC)模块,建立了PEMFC三维稳态数学模型并进行了车用怠速工况下的仿真研究。应用正交试验法,研究了燃料电池怠速性能的操作参数影响因素。在Fluent软件环境下分析了怠速工况和额定工况下燃料电池的内部流场,并分析了异同。实现对于燃料电池在怠速工况下运行性能的优化。The performance of a proton exchange membrane fuel cell （PEMFC） under idling condition is a key technical challenge restricting the PEMFC commercialization. This paper presented a PEMFC static mathematical model based on a computational fluid dynamics （CFD） solver, Fluent. An orthogonal experiment was conducted to find out the optimal combination of different operating parameters when tile fuel cell was running under idling condition. A three-dimensional simulation would also be done in order to analyze the physical illustrations in multiple channels as well as to compare the behavior of PEMFC with different current density. Idling performance of a fiiel cell is optimized for the fuel cell vehicle application.
