摘　　要：为了较好地对固体氧化物燃料电池(SOFC)进行快速动态仿真,建立了一维内重整SOFC的数学模型,在容阻特性建模和分布集总方法的基础上,对复杂的偏微分方程组进行了适用于快速仿真的一般差分方程组的转换,并建立了模块化的SOFC仿真模型.该模型考虑了气体属性沿电池长度方向的变化,能反映燃料电池的分布参数特性,并可满足实时动态仿真需求.仿真结果表明,容阻特性的建模方法在燃料电池系统中是可行的.Solid oxide fuel cell （SOFC） is a co trochemical reactions. This paper developed mplicated system with heat and mass transfer as well as elec the mathematical model of one dimension, direct internal reforming SOFC. The volume-resistance （V-R） characteristic modeling was introduced into the modeling of the SOFC system. Based on the V-R characteristic, the distributed-lumped method and modular idea, ordinary differential equations meeting the quick simulation were obtained from partial differential equations. This model considering the variation of local gas properties not only realizes the analysis of the distribution performance, but also satisfies the real time dynamic simulation. The results indicate that the V- R characteristic modeling is valuable and viable in the SOFC system.
