Major interest has been devoted to decrease the working temperature of solid oxide fuel cells (SOFCs) down to about 700 C. Apatite materials (La10-xSrxSi6O27-x/2) are attractive candidates for solid electrolytes, with a high ionic conductivity at 700 C, a chemical and a dimensional stability for a p...
