Operation of an LSGMC electrolyte-supported SOFC with composite ceramic anode and cathode

An all-perovskite-based intermediate-temperature fuel cell was fabricated from materials synthesized using glycine-nitrate process (GNP) combustion synthesis and modified Pechini synthesis routes. Yttrium-doped strontium titanate (SYT) was chosen as the conductive ceramic anode component to avoid problems associated with Ni-based anodes. La0.8Sr0.2Ga0.8Mg0.1Co0.1O3-delta electrolyte-supported solid oxide fuel cells (SOFCs) with composite ceramic anode and cathode exhibit a relatively high power density of 0.246 W/cm at 800 degrees C at 0.5 V.
