【摘要】 建立了一维基于催化涂层重整器的间接内重整固体氧化物燃料电池的动态数学模型。在组分和能量守恒的基础上,考虑了电化学模型,建立了基于分布集总参数技术和模块化思想的间接内重整固体氧化物燃料电池的仿真模型。该模型不仅能反映燃料电池的分布参数特性,还可以满足动态仿真的需求。利用该模型分析了某一工况下固体氧化物燃料电池的稳态性能,并进行了动态过程的仿真,结果证明该模型可以反映间接内重整固体氧化物燃料电池的基本性能。更多还原

【Abstract】 A one-dimensional dynamic mathematic model was established for a fuel cell based on a catalytic-coating reformer and featuring an indirect internally reformed solid oxide.On the basis of the constituents and energy conservation and with an electrochemical model being taken into account,a simulation model of the fuel cell in question was established based on the distributed-lumped parameter technology and modularization concept.The model under discussion can not only reflect the distribution parameter characteristics of the fuel cell but also meet the demand for dynamic simulation.The steady-state performance of a SOFC (solid-oxide fuel cell) was analyzed at an operating condition and the simulation of a dynamic process was conducted by using the model in question.The research results show that the model can reflect the basic performance of the indirect internally reformed SOFC.更多还原
