SOLID-OXIDE FUEL ELEMENT ELECTRODE AND METHOD OF ITS FABRICATION Russian patent published in 2010 - IPC H01M8/12 

FIELD: electrical engineering.

SUBSTANCE: proposed electrode applied on solid electrolyte layer consists of solid electrolyte particles with mixed or ion conductivity and porous sections of electrically conducting material from crystalline column structures of electrically conducting materials in contact with solid electrolyte particles and solid electrolyte layer surface via sublayer of electrically conducting clusters consisting of not inter-bonded agglomerates with size of 0.5-5 mcm that occupy 40 to 80% of solid electrolyte surface. Note here that agglomerates of cluster sublayer feature mixed electron-ion conductivity and are magnetron sputtered using two targets simultaneously made up of electrode material with electron conductivity and solid electrolyte material with ion conductivity with mass ratio varying from 12:1 to 8:1.

EFFECT: higher electrochemical efficiency of electrode and efficient generation of electric power.
