FIELD: chemistry.
SUBSTANCE: invention relates to composite oxygen electrode, containing porous structure of base, which includes two separate but percolated phases, with first phase representing electron-conducting phase and second phase representing oxide ion-conducting phase, and electrocatalytic layer on the surface of said structure of base, with said electrocatalytic layer containing first nanoparticles, representing electrocatalytically active nanoparticles and second nanoparticles, formed from ion-conducting material, with first and second particles being randomly distributed throughout electrocatalytic layer. Invention also relates to method of electrode obtaining.
EFFECT: claimed method possesses higher activity.
