FIELD: electrochemistry.
SUBSTANCE: invention relates to electrode materials based on praseodymium nickelide, which can be used in medium-temperature electrochemical devices, such as solid oxide fuel cells, electrolyzers, sensors, and others based on proton-conducting electrolytes belonging to the barium cerate-zirconate family. The material contains praseodymium nickelide, modified with copper, and has the composition Pr2Ni0.8Cu0.2O4+δ, and is characterized by a decrease in the temperature of baking on a proton-conducting electrolyte based on barium cerate-zirconates, which is the technical result of the invention.
EFFECT: modification of praseodymium nickelide with copper also improves adhesion with a proton-conducting electrolyte based on barium cerate-zirconates.
