Research progress of model simulation of direct internal reforming in solid oxide fuel cells
Solid oxide fuel cells (SOFCs) efficiently convert chemical energy into electric energy via electrochemical oxidation reactions, holding promise for various engineering applications in large-scale power generation, cogeneration, and integrated fuel upgrading. Direct internal reforming (DIR) technology, catalyzing alkanes like CH4 at the anode to produce H2, enhances SOFC application scenarios and reduces operational costs, thereby reducing fuel pretreatment requirements and improving conversion efficiency, which represents a hotspot in SOFC research. Model simulation studies aid in optimizing system design and operational conditions, reducing experimental work, and providing theoretical data support and guidance suggestions. Through the model simulation of the DIR–SOFC system, combined with the field distribution and kinetic parameters, the system reactions can be quantitatively evaluated to understand the complexity of physical and chemical processes. This paper summarizes the current situation of DIR-SOFC modeling work, introducing volume average and microstructural models. It discusses the multiscale mathematical model and reviews the description of the reaction dynamics process "energy-mass-momentum" balance equations as well as the description of the "1D-2D-3D" DIR-SOFC unit. This can be used to evaluate the variables on the DIR. Furthermore, it summarizes the reforming reactions of different liquid fuels in the DIR-SOFC model and the related reaction kinetic parameters. This study highlights existing model limitations and prospects for the future development of the DIR-SOFC system model to increase model accuracy.
