目前，有关各类电池的研究正在世界范围内迅猛开展，并已经取得了惊人的进步，而天然气作燃料应用于固体氧化物燃料电池则具有很大的发展前景。考虑不同操作条件、气体组成和电池微观结构的影响，建立了用于分析固体氧化物燃料电池发电特性的数学模型；浓差极化的计算采用尘气模型，用来描述多组分气体在多孔电极内的扩散过程；活化极化采用Butler-Volmer方程，欧姆极化遵循欧姆定律，采用MATLAB编写程序；进而结合计算结果讨论了阳极厚度、温度等对电池发电性能的影响，并与实验值进行了比较。

Electrical Performance Simulation of Electrolyte-supported Solid Oxide Fuel Cells

Recently, the study on different cells is being conducted rapidly and strongly in the world. And surprising progress has been achieved. It has bright future for the solid oxide fuel cells to use natural gas as fuel. Considering the influence of different operating conditions, gas compositions, and cell microstructures, the mathematical model to analyze the electrical performance of the solid oxide fuel cells is developed. The concentration polarization is calculated with the dusty gas model to describe the diffusion process of multi components gas in the porous electrode. The activation polarization is calculated by Butler Volmer equation. The Ohmic polarization follows the Ohm’s law. The codes are programmed using MATLAB. Then the influence of anode thickness and temperature on cell performance are analyzed using  calculated results, which are compared with experimental data.
