论文简介如下：
There are great interactions between the multi-physics fields distributing characteristics and the key structure factors within the solid oxide fuel cell (SOFC) stack. Understanding these secrets are important for the development of stack technologies referring to performance and duration. In this paper, the 3D large scale multi-physics model basing on the realistic solid, space and porous structures of a special designed 24-cells stack is successful developed with 15,656,579 specially designed meshes. The research result show that: i) adopting the 3-paralleled serpentine rib channels and discrete cylindrical rib channels for the anodic and cathodic surfaces, respectively, can well ensure relevant high fuel pressure and reactants distributing uniformities over the electrolyte surfaces; ii) the even and odd numbered interconnect plates are designed to have same structures and placed in different directions, which contribute to one fuel flow path and two separated 2in3out air flow paths. Each air flow path will in charge of the air feeding for half of the stack; iii) the trapezoidal distributor will feed the sub-inlet manifolds of each air flow path with similar mass flow rates. The corresponding fuel and air flows, hydrogen and oxygen, and temperature uniformities on both stack and single cell levels are calculated and analyzed.
