| 中文摘要 | A two dimensional numerical model of a solid oxide fuel cell (SOFC) with electrode functional layers is presented. The model incorporates the partial differential equations for mass transport, electric conduction and electrochemical reactions in the electrode functional layers, the anode support layer, the cathode current collection layer and at the electrode/electrolyte interfaces. A dusty gas model is used in modeling the gas transport in porous electrodes. The model is capable of providing results in good agreement with the experimental I-V relationship. Numerical examples are presented to illustrate the applications of this numerical model as a tool for the design and optimization of SOFCs. For a stack assembly of a pitch width of 2 mm and an interconnect-electrode contact resistance of 0.025 Omega cm(2), a typical SOFC stack cell should consist of a rib width of 0.9 mm, a cathode current collection layer thickness of 200-300 mu m, a cathode functional layer thickness of 20-40 mu m, and an anode functional layer thickness of 10-20 mu m in order to achieve optimal performance. |
