“…However, an exact knowledge of phenomenological properties like absorption coefficient, refractive index, scattering coefficient, emissivity, and reflectivity is not available and hence represents an obstacle in modeling radiative heat transport in SOFC electrodes and electrolyte. A detailed discussion of radiation heat transfer in SOFC is given elsewhere [13][14][15][16]. In an analysis of spectral radiation in SOFC electrodes, Damm and Fedorov [14] proved that the radiation effects in SOFC electrodes are minimal and can safely be neglected.…”
