摘　　要：对采用交指型流场的质子交换膜燃料电池阴极建立了二维数学模型,利用计算流体力学的方法,模拟和研究了质子交换膜燃料电池阴极内的流动和传质过程。分别探讨了采用交指型流场和平行流场时气体在阴极扩散层中的传递机制及各组分浓度分布的特性,为燃料电池流场的设计与分析提供了参考依据。　A two dimensional mathematical model was developed for the cathode of proton exchange membrane fuel cells（PEMFC） with interdigitated flow field.With computational fluid dynamics method,the flow and transport of gaseous species in the cathode of PEMFC were studied.The mechanism of gas transport in the cathode gas diffuser and the gaseous species concentration distribution in the cathode of PEMFC with interdigitated flow field and conventional flow field were discussed,respectively.These can be used for the design reference of PEMFC flow field.
