제목 A Thermodynamic and Electrical Behavior of La0.8Sr0.2ScxMn1xO3 Oxidesin a Reducing Environment
초록 Perovskite-type La0.8Sr0.2ScxMn1xO (LSSM) oxides (x=0.1~0.3) were synthesized by impregnation into the porous YSZ backbone for an electrode of intermediate temperature solid oxide fuel cell (SOFC). All materials were characterized by the thermodynamic properties such as the oxidation enthalpies and entropies through the Coulometric titration technique and electrical property via 4-probe method. Nonstoichiometric variations of oxygen content in La0.8Sr0.2ScxMn1xO and electrical conductivity were determined with wide range of P(O2) at the temperature of 923~1023K.The electrical conductivity of LSSM series was high enough to be good anode materials for SOFC.
