This work is among the first where the results of an extensive experimental research programme are compared to performance calculations of a comprehensive computational fluid dynamics model for a solid oxide fuel cell stack. The model, which combines electrochemical reactions with momentum, heat, and mass transport, is used to obtain results for an established industrial-scale fuel cell stack design with complex manifolds. To validate the model, comparisons with experimentally gathered voltage and temperature data are made for the Jülich Mark-F, 18-cell stack operating in a test furnace. Good agreement is obtained between the model and experiment results for cell voltages and temperature distributions, confirming the validity of the computational methodology for stack design. The transient effects during ramp up of current in the experiment may explain a lower average voltage than model predictions for the power curve.

这项工作是首次，其中将广泛的实验研究程序的结果与固体氧化物燃料电池堆的综合计算流体动力学模型的性能计算进行比较。该模型将电化学反应与动量，热和质量传递相结合，用于获得已建立的具有复杂歧管的工业规模燃料电池堆设计的结果。为了验证该模型，对在试验炉中运行的18格JülichMark-F电池与实验收集的电压和温度数据进行了比较。该模型与电池电压和温度分布的实验结果之间取得了良好的一致性，证实了堆叠设计计算方法的有效性。
