abstract

A computational fluid dynamics model is developed to study the effects of operational parameters on the performance of a micro-tubular SOFC. Coupled partial differential equations for heat, momentum, species and charge balances are solved with a commercial software using finite element method. Effect of temperature on the power characteristics of the system is addressed. Current density distributions for different temperatures are compared with the inclusion of electronic leakage currents in the electrolyte. Current density profiles for different conditions are examined thoroughly and related to the transport properties.
