| 中文摘要:为了评估玻璃/Al2O3基复合密封材料在固体氧化物燃料电池（SOFC）中的密封性能，本研究利用FLUENT软件，基于多孔介质模型，对用于SOFC内部连接体和电极之间的该密封材料的泄漏量进行了模拟仿真。结果表明：采用的计算模型和模拟方法是可行的；泄漏量的大小与压力的变化正相关，与温度的变化为负相关；物性参数的差异是影响气体介质泄漏量发生变化的主要因素。通过实验的对比分析，说明本研究采用的计算模型及模拟方法正确可行，这为预测SOFC的密封泄漏提供一种可靠的评价方法。 |

| Abstract:In order to evaluate the sealing performance of glass / Al2O3 matrix composite sealing material in solid oxide fuel cell (SOFC), the leakage rate of the sealing material between the internal connector and the electrode of SOFC was simulated by FLUENT software based on the porous medium model. The results show that the calculation model and simulation method are feasible; the leakage is positively correlated with the change of pressure and negatively correlated with the change of temperature. The difference of physical parameters is the main factor affecting the change of gas medium leakage. Through the comparative analysis of experiments, it shows that the calculation model and simulation method used in this study are correct and effective, which provides a reliable evaluation method for predicting the seal leakage of SOFC. |
