【摘要】 本文探讨熔融碳酸盐燃料电池(MCFC)的多组分电化学反应和传热传质机理。建立了熔融碳酸盐燃料电池堆内部单体的暂态温度模型，并考虑了电堆的辐射换热、转换反应、反应气体组分变化对温度场的影响；根据MCFC的微分控制方程组，考虑气体组分的热力学性质及动量变化的影响，利用数值分析方法求解熔融碳酸盐燃料电池堆的三维流场与温度场，分析了各作用因素对熔融碳酸盐燃料电池堆温度分布的影响机制。更多还原

【Abstract】 Studying the heat-mass transfer and multi-spices electric-chemical reaction, a dynamic temperature model was deduced for molten-Carbonate fuel cell stack. The thermal radiation, shift reaction, and the change of gas spices were considered in this model. Establishing momentum equation, the paper has developed a 3D temperature and flow fields model for MCFC stack based on CFD technique. The change of momentum and thermal property were considered in this model. Detail results of temperature and flow fields have been got through solving model by different methods. The predominant effect factors on the temperature of MCFC stack ware also analyzed in the paper.更多还原
