摘要：

固体氧化物燃料电池(SOFC)阳极积碳是制约其高效稳定运行的瓶颈问题，文中回顾了国内外学者在实验领域对SOFC积碳问题的研究进展，并指出研究积碳产生速率数学模型的意义。搭建了由气路管道，气体流量控制器，开启式真空气氛管式电加热炉等仪器设备组成的固体氧化物燃料电池积碳测试实验台；介绍了实验用片状阳极材料的制备，以及积碳实验的详细步骤。基于对镍/氧化钇稳定氧化锆(Ni/YSZ)金属陶瓷阳极上一氧化碳(CO)积碳特性的实验结果分析了：①一氧化碳/二氧化碳(CO/CO₂)混合气体组分对CO歧化反应积碳特性影响；②温度对CO歧化反应积碳特性影响；③甲烷(CH₄)裂解与CO歧化对积碳特性的影响。本文最后基于化学反应动力学，推导了不同温度下CO歧化反应积碳速率数学计算模型，并运用实验结果对其进行了验证。本文研究有助于探索SOFC积碳产生的机理，同时为以天然气为燃料的SOFC运行参数最优化控制提供了依据。

Abstract:

The occurrence of carbon deposition on the anode of a solid oxide fuel cell (SOFC) is the bottleneck restricting its efficiency and stabilization. This paper reviews the research progress on the carbon deposition of SOFC in the experimental field both at home and abroad and points out the significance of determining a mathematical model of the carbon deposition rate. The SOFC carbon deposition experimental system is constructed composed of a gas pipeline, gas flow controller, open vacuum atmosphere, tubular electric heating furnace, and other instruments and equipment. The preparation of the sheet anode material for the experiment and the detailed steps of the carbon deposition experiment are introduced. We obtained the following based on the experimental results of the carbon deposition characteristics of the CO on Ni/YSZ anode: (1) the effect of CO/CO₂ volume fraction on carbon deposition characteristics of CO disproportionation reaction; (2) effects of temperature on carbon deposition characteristics of CO disproportionation reaction; (3) effects of CH₄ scission reaction and CO disproportionation on carbon deposition characteristics. Finally, based on the chemical reaction kinetics, the mathematical calculation model of the carbon deposition rate of CO disproportionation reaction at various temperatures is deduced and verified by the experimental results. This study is helpful to explore the mechanism of carbon deposition in an SOFC and provides a basis for the optimal control of SOFC operating parameters with natural gas as fuel.
