Abstract
A multi-dimensional model has been established to
investigate the performance of anode-supported SOFC fuel cell
with two different configuration, :i) the Anode Supported Planar
Solid Oxide Fuel Cell (ASP_SOFC) with channel gas surface
1mm2 and ii) ASP_SOFC with channel gas surface 0.25mm2. The
numerical simulation was realized with a SOFC fuel cell model
based on the ANSYS FLUENT computational fluid dynamics
(CFD) software. The simulation results were illustrated
polarization curves including J–V,J–P, Ohmic and activation
over-potential curves. It was found that the increase in channel
surface has more significant influences on the cell performance.
The model is validated using one of the available numerical
results from previous researches the comparison between the
numerical model and the reported results shows very good
agreement.
