The Impact

A considerable design and operational challenge for solid oxide fuel cells (SOFCs) is the material degradation caused by high temperature (600–1000°C) operation. At such high temperatures, it is reasonable to assume that radiative heat transfer effects may be significant; however, few studies have rigorously investigated the impact of radiative heat transfer on the operation of SOFCs. Accordingly, modeling efforts have been made to characterize the temperature profile evolutions that occur within planar SOFCs during transient operation. Therefore, initial results are presented to elucidate the impact of radiation upon SOFCs during start up, load changes, and shut down.
