SOLID OXIDE COMPOSITE MATERIAL FOR ELECTROCHEMICAL DEVICE MEMBRANES Russian patent published in 2014 - IPC C04B35/47 C04B35/40 B01D71/02

Abstract RU 2510385 C1

FIELD: electricity.

SUBSTANCE: solid oxide composite material for membranes of electrochemical devices contains strontium titanate-ferrite and is a composite based on co-doped cerium oxide and strontium titanate-ferrite, the composition of which has the formula (1-x)Ce_0.8(Sm_0.8Sr_0.2)_0.2O_2-δ - xSrTi_0.5Fe_0.5O_3-δ, where x=0.25; 0.50; 0.75. The material has properties that are typical for individual phases.

EFFECT: high stability of the material in a reducing atmosphere while maintaining or increasing mechanical strength and overall electroconductivity.
