SOLID OXIDE CELL AND BATTERY CONTAINING SAME Russian patent published in 2014 - IPC H01M8/00 H01M8/12 

FIELD: chemistry.

SUBSTANCE: present invention relates to solid oxide fuel cells made using a method comprising the following steps: depositing a fuel electrode layer; an electrolyte layer containing stabilised zirconium on the fuel electrode layer to obtain a system consisting of a fuel electrode base and an electrolyte; sintering the system of the fuel electrode base and the electrolyte with each other to obtain a half cell; depositing, on the electrolyte layer of a pre-sintered half-cell, one or more oxygen electrode layers, wherein at least one of the layers contains a composite of lanthanum-strontium-manganite and stabilised zirconium to obtain a full solid oxide cell; sintering the one or more oxygen electrode layers with the pre-sintered half-cell; and saturating the one or more oxygen electrode layers of the full solid oxide cell with manganese to obtain a manganese-saturated fuel cell. Also disclosed is a battery containing one or more solid oxide cells made using the disclosed method.

EFFECT: longer life of said fuel cell.
