Simulation results for MCFC temperature and voltage distribution, conversion and performance, including and excluding the water-gas shift reaction, were compared. The shift reaction caused the temperature profile to become non-uniform. At the entrance, hydrogen was consumed rapidly to reach equilibrium in the shift reaction. Hydrogen conversion decreased along the gas flow because of hydrogen generated by the shift reaction. Therefore, hydrogen conversion was higher than in a practical cell when the shift reaction is excluded. At the same current density, the voltage calculated without the shift reaction would be higher than the "real" value. The effect of the shift reaction on voltage distribution and cell performances was quite small.
