摘要

直接碳固体氧化物燃料电池(Direct Carbon Solid Oxide Fuel Cells

DC-SOFCs)是一种能将固体碳燃料的化学能直接转化为电能的高效发电装置。模型研究对DC-SOFCs技术发展具有重要的指导意义，但目前DC-SOFCs的模型研究均为稳态模拟，难以解析DC-SOFCs性能随时间的演变。针对该问题，利用缩核模型模拟固体碳燃料的消耗，结合缩核模型和多物理场耦合模型开展DC-SOFCs动态特性研究，模拟电池运行过程中的动态变化，从而评估碳燃料的消耗对电池性能和稳定性的影响。研究结果表明：碳颗粒尺寸随时间的推移而逐渐减小，使阳极腔室CO浓度发生变化，进而影响DC-SOFCs性能；较小的碳颗粒有助于提高电池性能，但其消耗速率较快；碳颗粒较大的电池初始性能相对较低，但电池能保持较为稳定的输出性能。

Abstract

Direct carbon solid oxide fuel cells (DC-SOFCs) are highly efficient power generation devices that can directly convert the chemical energy of solid carbon fuel into electrical energy. Modeling research has important guiding significance for the development of DC-SOFCs technology. However

current models of DC-SOFCs are steady-state simulation

which makes it difficult to analyze the evolution of DC-SOFCs performance over time. To address this problem

the consumption of solid carbon fuel is simulated by using the shrinking core model. The dynamic simulation of DC-SOFCs is carried out by combining the shrinking core model and the multiphysics coupling model to simulate the dynamic changes during the operation of cells. The impact of carbon fuel consumption on cells’ performance and stability is evaluated. The results show that the size of carbon particles gradually decreases over time

causing the change of CO concentration in the anode chamber

which in turn affects the performance of DC-SOFCs. Smaller carbon particles help improve the performance of cells

but their consumption rate is faster. The initial performance of cells with larger carbon particles is relatively low

but a relatively stable output performance of cells can be maintained.
