Abstract

This paper describes a numerical analysis for comparing the performance of two geometrically different solid oxide fuel cells (SOFC), i.e. tubular-type and planar-type SOFCs. The analysis uses a custom-developed computer code which is capable of simulating the complete energy conversion process in SOFC, including fuel reforming and water shift. The detailed numerical procedures are based on strong coupling of electrochemistry, electricity, material properties and transport phenomena. This simulation effort is followed by an optimization study to further enhance the power density of anode-supported planar SOFC. The optimization procedure is to identify optimal combination of the size of current collector and its domain of influence.
