| 摘 要： | 建立了平板式固体氧化物燃料电池多场耦合数学模型,利用商业CFD软件FLUENT对包括阳极和阴极多孔介质、致密固体氧化物电解质、燃料流道、氧化剂流道、电流收集双极板、外壳的单电池三维整体计算区域进行了数值模拟,得到了流场、温度场、组分浓度场、电流密度场、Nernst电动势、活化过电势和欧姆过电势等重要物理量的详细分布,并分析了影响电池性能的主要因素。模拟结果与SOFC研制单位提供的实验数据基本符合。

| Abstract: | A coupled multi-fields model was built for an anode-supported planar solid oxide fuel cell (SOFC).Numerical simulation was performed for the overall 3D domain of a single cell including the anode and cathode porous media,the dense solid oxide electrolyte,the fuel and oxidant passages,the bi-polar current collectors and the housing using a commercial CFD code FLUENT.The detailed distribution of the flow,the temperature,the species concentration,the current density,the Nernst potential,the activation over-pot... |
