CATHODE MATERIALS FOR SOLID OXIDE FUEL CELLS BASED ON NICKEL-CONTAINING LAYERED PEROVSKITE-LIKE OXIDES Russian patent published in 2015 - IPC C25B11/04 H01M8/10 H01M4/131

Abstract RU 2553460 C2

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 0.0<x<1.0; 0.0<y<1.0; -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.
