摘　　要：本文以多通道平板式阳极支撑固体氧化物燃料电池为研究对象,利用能量守恒、物质守恒、动量守恒方程,结合燃料电池的工作原理,利用多物理场耦合软件COMSOL建立了三维多通道逆流稳态单电池模型。此次研究主要针对逆流流场,计算其速度场分布、摩尔浓度分布、电流密度分布等情况,进而讨论流道速度、组分浓度、电池片结构对电池性能的影响,分析这些不同参数存在的内在联系,更好地为平板式阳极支撑固体氧化物燃料电池的工作状态控制和结构优化设计提供理论支持。This paper studied the multi-channel planar anode-supported solid oxide fuel cell(SOFC).The simulation model of a threedimensionalmulti-channel counter-flow steady-state SOFC was built based on multi-physics coupling model in COMSOL software by usingmathematical models of energy conservation,mass balance and momentum conservation combined with the operating principle of SOFC.The distributions of velocity,concentration and current were calculated to discuss their respective influence on the performance,and the innerconnections among the different parameters were analyzed at the same time,which would lay the foundation for optimizing the control of theoperation conditions and the design of the structure.
