A 1‐D electrochemical model for a solid oxide electrolysis cell (SOEC) is developed and validated using published experimental data. The model combines thermodynamics, kinetic, ohmic, and concentration overpotentials to predict cell performance. For the anode‐supported SOEC, good agreement is obtained between the model and experimental data, with ohmic loss being the major contributor to the cell's total overpotential. Both kinetic and concentration losses are less significant due to high‐temperature operation. Due to the dominating performance loss, reducing the anode thickness is effective in diminishing the cell potential. Overall, this simple 1‐D model can be employed as a design tool to evaluate component design and estimate system performance for industrial applications.

阳极支撑的固体氧化物电解槽的实验和分析研究

使用公开的实验数据开发并验证了固体氧化物电解槽（SOEC）的一维电化学模型。该模型结合了热力学，动力学，欧姆和浓度超电势来预测电池性能。对于阳极支撑的SOEC，模型与实验数据之间取得了良好的一致性，其中欧姆损耗是电池总超电势的主要因素。由于高温运行，动力学损失和浓度损失都不太明显。由于主要的性能损失，减小阳极厚度可有效减小电池电势。总体而言，该简单的一维模型可以用作设计工具，以评估组件设计并评估工业应用的系统性能。
