中文摘要:
      分块化方法是将单片质子交换膜燃料电池(Proton Exchange Membrane Fuel Cell,PEMFC)沿阳极和阴极流道划分成15个连续的子模块;然后,将每个子模块视为一个独立的PEMFC集总模型,用第n个子模块的输出(即气体摩尔流量和压力)作为第n 1个子模块的输入,最终获得单片PEMFC内部的电流密度分布和膜中水含量分布。基于此建模方法,分别建立了稳态和动态的分块化PEMFC仿真模型,仿真结果对比表明,动态分块化PEMFC模型不仅能预测电流密度分布和膜中水含量分布,而且能较为合理的描述PEMFC的动态特性。
英文摘要:
      The segmented method is used by separating a single PEMFC (proton exchange membrane fuel cell) into 15 continuous segments, along the flow channel of the anode and cathode. Each segment is treated as an independent lumped submodel, and the outputs (i.e.molar flow rate and pressure) of the nth segment becomes the inputs of the (n 1)th segment. By this way, the distributions of current density and membrane's water content over a single cell can be predicted. Based on this method, a dynamic and steady segmented PEMFC model are developed separately, and their performances are evaluated by simulation. Comparing with the steady segmented PEMFC model, the dynamic one can not only predict the distribution of current density and water content in membrane, but also is able to describe the transient characteristics of the PEMFC.
