CATHODE MATERIALS FOR SOLID OXIDE FUEL CELLS BASED ON NICKEL-CONTAINING LAYERED PEROVSKITE-LIKE OXIDES

摘要

FIELD: chemistry.;SUBSTANCE: invention relates to a cathode material for solid oxide fuel cells (SOFC) based on nickel-containing perovskite-like layered oxides. As perovskite-like oxide, taken is a compound of the general formula Pr_2-xSr_xNi_1-yCo_yO_4-z, where 0.0x1.0; 0.0y1.0; -0.25≤z≤0.25.;EFFECT: cathode material possesses simultaneously high oxygen-ion conductivity, which has the value of the thermal expansion coefficient (TEC), close to TEC of the SOFC electrolyte.;1 ex, 2 dwg
