METHOD OF OBTAINMENT OF SOLID OXIDE FUEL CELL WITH DOUBLE-LAYER CARRIER CATHODE Russian patent published in 2014 - IPC H01M8/02 H01M8/10 

FIELD: electricity.

SUBSTANCE: method of obtainment of solid oxide fuel cell with double-layer carrier cathode involves electrode and collector layer forming and baking. A layer of solid electrolyte stabilised by yttrium (YSZ) is applied onto electrode layer of cathode and baked, Anode is applied onto electrolyte layer, then the element is baked, and collector layer of cathode is formed by lanthanum strontium manganite powder and electrode layer is formed out of a mix of lanthanum strontium manganite and zirconium oxide powders stabilised by yttrium oxide. Collector layer is annealed at 1350°C for 2 hours, electrode layer in the form of alcohol suspension of the mix of lanthanum strontium manganite and zirconium oxide powders stabilised by yttrium oxide is applied on the resulting layer, the layers are baked at 1200°C for 2 hours after electrolyte is baked to electrode layer and anode is baked to electrolyte layer. At the side of collector layer, cathode is impregnated with aqueous solution of praseodymium nitrate in amount of 15-20 wt % of cathode weight and heated at 100°C/hour rate to 600°C with maturing for 1 hour in air.

EFFECT: enhanced specific power of hydrogen/air solid oxide fuel cell with double-layer carrier cathode proposed.
