Modeling of Disk-Shaped Anode-Support SOFC with Proton Conductor Electrolyte and Sm_0.5Sr_0.5CoO_3-δ-Sm_0.2Ce_0.8O_2-δ Cathode

Abstract:

A concise model for disk-shaped solid oxide fuel cell (SOFC) with proton conductor electrolyte was developed by concerning relevant polarizations. Sm_0.5Sr_0.5CoO_3-δ- Sm_0.2Ce_0.8O_2-δ was taken as an example for cathode material. Proportions of each polarization were identified separately. Two important capacities, namely max power density and limit current density were discussed. Some suggestions to improve the cell performance were made. Comparison between proton and oxygen conductor electrolyte was discussed.
