Abstract :
In the present study various three dimensional computational fluid dynamic (CFD) models of planar solid oxide fuel cells have been developed. All the transport equations as mentioned were discretized using the finite volume (FV) method. The developed model is then validated using the experimental data at the same conditions obtained from the literature. Two types of models were developed in this study. First one was relevant to a single channel solid oxide fuel cell for investigation of operating, structural and geometrical parameters such as temperature, pressure, relative humidity, porosity, electrolyte and anode electrode thickness on the fuel cell. Furthermore, the second models with 13 flow channels in anode and cathode sides was used for flow arrangement study. Results of parametric study showed that temperature and pressure, anode and electrolyte thickness and flow channel aspect ratio significantly influence on solid oxide fuel cell performance. Flow arrangement study showed that co-flow arrangement had the best performance.
