Solid oxide fuel cell (SOFC) is a emerging electricity generation technology with high efficiency and environmental friendliness. Planar anode-supported SOFC is one of the promising types of SOFC because of the low electrical resistance and flexible assembly. Modeling simulation can provide theoretical support and technical guidance for the development and optimization of the planar anode-supported SOFC. This paper focused on the planar anode-supported SOFC and presented a detailed discussion of both the geometric model and the single repeat unit (SRU) model. The geometric model enabled structural and property analyses of various typical planar anode-supported SOFC configurations, which was crucial for establishing a robust foundation for modeling research. The SRU model allowed for the simulation of individual cell structures and could be used to predict the performance of the entire stack based on the behavior of a single unit. However, most existing SRU models were based on idealized or simplified assumptions, and certain electrochemical reaction mechanisms remained poorly understood. Future modeling efforts should focus on multiphysics equations description, experimental data collection, and validation under real-world operating conditions in order to improve model accuracy and reliability.
