Abstract
As known one of the most drawbacks of solid oxide fuel cell (SOFC) is high operation temperature (i.e., 800 0C). One of the suggested remedies is to replace the oxygen ion conducting electrolyte with proton ion conducting one. The purpose of the current study is to numerically study the effect of operating parameters such as inlet fuel, oxidant temperature, and inlet oxidant flow rate on the performance of a two-dimensional micro-planar proton conducting SOFC. Fuel is a mixture of methane, hydrogen, carbon monoxide, carbon dioxide and water (so there are internal reforming and water-gas shift reactions). An inhouse computational fluid dynamics code is utilized to solve the nonlinear governing equations of mass, momentum, energy, charge balance and gas-phase species coupled with kinetics equations. Results show that an increase in inlet fuel and oxidant temperature decreases the efficiency of a proton-conducting solid oxide fuel cell which is a due rise in temperature gradient along the cell length. In addition, the increase in oxidant flow rate improves the electrochemical reaction in the cathode side and causes the reduction in operating temperature of proton conducting SOFC.
