Abstract:
In this work, a model was presented for an MCFC fuel cell with internal reforming and combustion chamber. The model consists of mass and heat transfer equations beside the chemical and electrochemical reaction rate equations. Velocity distribution due to reactions and temperature distribution along the cell is considered. The model has been simulated in steady state form using finite difference method in MATLAB package environment accompanied by the analysis of the dynamic behavior of cell using method of lines in Simulink environment. Simulation results have been validated with experimental data extracted from literature. The last part of the work concerns with sensitivity analysis of some chemical parameters in the model. Results from this analysis show that chemical parameters related to cathode channel, have greater effect on current density than anade channel parameters. On the other hand, changing heat capacity of gaseous phases in channels change current density of the cell in all points in the cell, but changing activation energy changes current density in maximum points more than others
