固体氧化物燃料电池（SOFC）是一种高效的电化学发电装置，并具有高度的燃料灵活性，能够内部干重整CH4和CO2，实现合成气与电的共产。为提升SOFC内干重整效率与长期稳定性，可在阳极设置甲烷二氧化碳干重整催化层来提供额外的重整能力。但目前对干重整层的催化反应机理研究尚停留在非均相催化层次，相关的动力学模型忽视了电化学强化催化效应（EPOC）的影响。本项目拟开展EPOC效应影响下的经典Ni/GDC催化层动力学研究，建立Ni/GDC催化层微观结构模型、传热传质传荷模型，电学基本性质（电子电导率，离子电导率）模型，并配合多物理场数值仿真辅助拟合，获得准确的电化学强化干重整动力学模型，明确其催化反应机理，并利用该模型开展全电池参数化研究，明确全电池工作工况、电极微结构、载体性质等对干重整过程的影响规律，并提出相应的优化准则，指导高性能甲烷干重整SOFC的开发。

The solid oxide fuel cell (SOFC) is a highly efficient electrochemical power generation device and has a high degree of fuel flexibility. It can internally reform CH4 and CO2 to achieve the co-production of syngas and electricity. In order to improve the efficiency and long-term stability of dry reforming, an additional dry reforming layer can be applied at the anode to provide additional reforming capacity. However, the current research on the catalytic reaction mechanism of the dry reforming layer is still at the level of heterogeneous catalysis, and the relevant catalysis models ignore the effect of the electrochemical promotion of catalysis (EPOC). This project intends to study the catalytic kinetics of classic Ni/GDC dry reforming layer considering the EPOC effect. The microstructure model, heat and mass transfer model, model of electrical properties (electron conductivity, ion conductivity) would be built through experimental measurements for the establishment of an accurate electrochemical enhanced dry reforming kinetic model by multi-physics numerical simulation assisted fitting method. This model would be used to carry out parametric study for full-cell, exploring the influence of operating conditions, electrode microstructure, support properties, etc. on dry reforming process, and propose corresponding optimization guidelines for the development of high-performance methane dry reforming SOFC.
