The multi-scale, multi-physical and chemical SOFC working process couples flow, mass transfer, reaction and heat transfer together. This paper studies the distribution characteristics of physical quantities inside industrialized reactors. A fully coupled multi-field model of a full-size battery short stack is established, which truly reproduces the distribution of various physical fields inside the stack, and analyzes the impact of the shunt on the stack, illustrating the importance of full coupling of the stack model components. It has important reference significance for understanding and studying the close relationship between stack working conditions and discharge performance. The research results show that the inhomogeneity of the stack is mainly caused by the inhomogeneity of the flow field.
