METHOD FOR OBTAINING STRUCTURES FOR SOLID OXIDE ELECTROCHEMICAL DEVICES Russian patent published in 2022 - IPC H01M8/124 

FIELD: undeformed layered structures obtaining.

SUBSTANCE: invention relates to a method for obtaining undeformed layered structures - half-cells, which can be used as the basis of solid oxide electrochemical devices, such as, for example, solid oxide fuel cells (SOFC) and electrolyzers (SOC). The method includes the formation of films from a dried mixture of solid oxide material powder with an organic binder and a dried mixture of solid oxide material powder with an organic binder and starch, which are then jointly rolled to obtain a structure containing a dense and porous layers, while using an organic binder based on nitrile rubber. , and zirconium oxide stabilized with yttria is used as a solid oxide material, the resulting two-layer structure is annealed at a temperature of 1500-1600°C, the porous layer of the annealed structure is impregnated with a solution of nickel nitrate, followed by firing at a temperature of 600°C, while the impregnation and firing of the porous layers are repeated 8 to 10 times.

EFFECT: simplifying the production of undeformed half-cells used as the basis of solid oxide electrochemical devices.
