FIELD: electrical engineering.
SUBSTANCE: invention relates to highly porous electrode materials based on neodymium nickelate, which can be used as air electrodes for electrochemical devices based on proton-conducting electrolytes, including solid oxide fuel cells, sensors and electrolytic cells. Material is nickelate of neodymium, doped with barium and fluorine, of composition: Nd1.9Ba0.1NiO4+δFx, where x = 0.05.
EFFECT: invention enables to obtain solid oxide electrode material with reduced values of temperature coefficient of linear expansion, reduced effect of chemical deformation on thermomechanical properties of material and reduced values of polarization resistance.
