Quantification of the Radiative and Convective Heat Transfer Processes and their Effect on mSOFC by CFD Modelling

Quantification of the Radiative and Convective Heat Transfer Processes and their Effect on mSOFC by CFD Modelling

The CFD modelling of heat transfer in a microtubular Solid Oxide Fuel Cell (mSOFC) stack has been presented. Stack performance predictions were based on a 16 anode-supported microtubular SOFCs sub-stack, which is a component of the overall stack containing 64 fuel cells. Both radiative and convectiv...
