Abstract

In this study, a more accurate model of fuel cell of molten carbonate was also used that was determined input and output control variables and investigated the behavior of the system with respect to those variables. A more complete kinetic is also implemented for increasing the effectiveness of the presented paper. The input variables include fuel flow rate of cell which is methane and cell voltage. The output of the model is the flow resulting from the cell that is function of electrochemical reaction rate and accordingly, function of state variables quantities. In the following, the model in every input under change of step was simulated and analyzed dynamic behavior of cell. This indicates that as fuel flow rate into the cell is less, the productivity of fuel gets higher. Also, in the analysis of fuel cell, it has seen that temperature of molten carbonate depends strongly on the amount of combustion of compositions in the combustion chamber. As inlet concentration of methane, hydrogen and carbon monoxide is more, the heat liberated from combustion is more and system temperature gets high which results in increasing of thermal stress in molten carbonate fuel cell.
