As the fabrication technology of the composite electrode becomes sophisticated, the understanding of the detailed knowledge of the microstructure’s effect on the electrochemical process is essential for the commercializing of the solid oxide fuel cell (SOFC). In this paper, an equivalent circuit for the SOFC structure is proposed to clearly describe the electronic electric current transfer process, ionic electric current transfer process and the charge transfer process at the electrochemical reaction interface between electronic and ionic conducting materials. And types of the boundary condition setting constraints for the developing of the multi-physics coupling numerical model of SOFC are obtained basing on the electrochemical kinetic analysis.
