摘要:

宏观数值仿真方法通过耦合多个物理场可对固体氧化物燃料电池(solid oxide fuel cell,SOFC)进行仿真,在研究SOFC内部机理、外部输出性能等方面存在优势,可为电池优化设计提供依据。SOFC内部气体流动的均匀性直接影响电池效率,热场的分布会影响电池的发电性能和长期稳定性。本文总结了SOFC内部流道、外部歧管对流场的影响、优化传统流道以及设计新型流道中的宏观数值仿真模拟,以及宏观尺度数值仿真在热量传输和热稳定性方面的研究进展;概括了宏观数值模拟在分析燃料效率,结合多尺度模型,以及设计SOFC组件及新结构方面的研究进展。对应用宏观数值仿真方法研究SOFC进行总结和展望,认为目前需要统一SOFC结构设计的评价标准,以便量化对比。

Abstract:

The macroscopic-scale numerical simulation method can simulate solid oxide fuel cells (SOFCs) by coupling multiple physical fields. It has advantages in studying the internal mechanism and external output performance of SOFCs, providing a basis for the optimization design of cells. The gas flow uniformity inside SOFCs directly affects the battery's efficiency, and the thermal field distribution will affect the power generation performance and long-term stability of the battery. This paper summarizes the research progress of the influence of the internal flow channel and external manifold of SOFCs on the flow field, optimization of the traditional flow channel, and design of a new flow channel, and macroscopic-scale numerical simulation in heat transport and thermal stability. Furthermore, the research progress of macroscopic-scale numerical simulation in analyzing fuel efficiency, coupled multiscale model, and designing SOFC components and new structures are reviewed. The application of macroscopic numerical simulation methods in studying SOFCs is summarized and prospected. It is considered necessary to unify the evaluation criteria of SOFC structure design for quantitative comparison.

Key words: solid oxide fuel cell, numerical simulation, flow field design, thermal simulation, performance optimization
