A large-scale stack model of a molten carbonate fuel cell was developed for evaluating the variation of cell performance and temperature in the cell-stacking direction. A numerical method for the performance and three-dimensional temperature distribution in the stack was proposed and examined. For the temperature distribution, calculated results, taking the heat transfer at the end plate surface into account, were compared with the measured temperature distribution of the cell stack with good agreement. For several stacks composed of 12 cells with different gas flow configurations, the total stack performance and the temperature distribution were investigated analytically. The temperature distribution of the cell becomes more uniform due to the effect of heat exchange in the stacking direction.
