| Summary: | A mathematical model is developed to study the performance of a direct carbon solid oxide fuel cell system (DC-SOFC). Simulation results indicate that in the anode supported configuration, anode design parameters (porosity, tortuosity and anode thickness) play very important role in the performance of DC-SOFC, presented as the polarization curve. The effect of Ag content in anode electrode is found to play a significant role in the performance of the DC-SOFC. The effect of operating parameters, namely pressure and temperature, on the overpotentials (concentration, activation and ohmic) are studied. The concentration profiles of gases (CO2 and CO) as a function of operating current density across the anode electrode is studied. Model results are compared with experimental data and found to compare well.
