B.Rousseau, H.Gomart, D.De Sousa Meneses, P.Echegut M.Rieu, R.Dugas, P.Lenormand, F.Ansart, 'Modelling of the radiative properties of a porous ceramic layer', J. Electroceram. 27 89-92 (2011) doi:10.1007/s10832-009-9595-6
Solid Oxide Fuel Cells (SOFCs) operate at temperature above 1100 K where radiation effects can be significant. Therefore an accurate thermal model of an SOFC requires to include the contribution of thermal radiation. This implies that the thermal radiative properties of the oxide ceramics used in the design of SOFCs must be known. However, few data can be found in the literature at their operating temperatures. In the other hand, several types of ceramics with different chemical compositions and microstructures are now tested for designing efficient cells. This is the kind of situation where the use of a numerical tool allowing the prediction of the thermal radiative properties of SOFC materials whatever their chemical composition and microstructure, may be a decisive help. In this way, first attempts to predict the radiative properties of a lanthanum nickelate porous layer deposited onto an yttria stabilized zirconium substrate are reported.
