摘要：
We developed a three dimensional (3-D) mathematical model for a cell stack to perform comprehensive CFD analyses of degradation over a long period of time. The constructed 3-D CFD model consists of complete components in a practical SOFC stack. We calculated the concentration of the chemical species, the temperature distribution, the potential distribution, and the current density for each part of the stack. We also calculated the incremental electrical resistance using empirical formulas and predicted the change of electrical output and stack temperature distribution caused by degradation.
