摘要： 计算机模拟是燃料电池设计的一个重要辅助工具。本文在分析了燃料电池的电学和热学性质之后,设计了一套二维平板型团体氧化物燃料电池(SOFC)的模拟软件,软件能回答诸如温度场分布、电流场分布、输出功率等问题,作为应用例子,该软件被用于分析比较不同气流流向(交叉流、并流、对流)设计的燃料电池工作情况,指出了它们的优缺点,为燃料电池设计提供了有益的信息。

Abstract: Computer simulation is an important tool for fuel cell designs. Based on the fuel cell electrochemistry and thermal analysis, a 2D modeling software for planar solid oxide fuel cell (SOFC) was created. The software can evaluate quantities such as temperature distribution, current density profile, output power, etc. As a case study, the model was used to analyze the operating characteristics of fuel cells of different gas flow patterns, providing useful information for the fuel cell designs by revealing their merits and shortcomings.

Key words: fuel cell, electrochemistry, thermal balance, computer simulation
