Shortcomings: Solid electrolyte does not have good conductivity, so this cell must operate at high temperature like 850 Celsius degree to ensure enough diffusivity of oxygen. CH. 4. can also be introduced as the fuel for anode. Because SOFC cell operates at high temperature, so CH. 4 . gas will decompose into H2 and CO. In that case, the reactions

booksite.elsevier.comThe thermal conductivity is a property of the material and, as such, it is not really a constant, but rather it depends on the thermodynamic state of the material, i.e., on the temperature and pressure of the material. However, for solids, liquids, and low-pressure gases, the pressure dependence is usually negligible.

cds.cern.chThe resulting temperature profile T (x) is linear. However, the thermal conductivity depends on temperature, especially in the cryogenic domain, leading to nonlinear profiles- (see Fig. 4). Simply put, heat is transported in solids by electrons and phonons, and the thermal conductivity is seen as the sum of both contributions:
