A numerical model to analyze the internal conditions of a MCFC stack has been modified to estimate single electrode heating value. Magnitude of heat that evolves on the cathode and reabsorbed on the anode has similar order to an electrical output from MCFC. A temperature distribution in the electrolyte plate has been studied applying thermodynamics of irreversible process. Calculated temperature distribution has been compared with the temperature distribution without single electrode heat effect. Calculated absolute value of Thomson coefficient in the MCFC electrolyte plate has been evaluated to be lower than 0.1mV/K. Finally, temperature differences between cathode and anode have been estimated for the different thermal conductivity of electrolyte plate. The temperature difference between two electrodes are calculated to be small value under the normal operating condition of MCFC.
