FIELD: materials for electrochemical devices.
SUBSTANCE: production of solid oxide electrolyte materials with proton conductivity based on barium-neodymium indate (BaNd4In2O7), which can be used as an electrolyte material in proton-conducting solid oxide fuel cells used to generate electricity. The material is barium-lanthanum indate doped with praseodymium and has the following composition: BaLa0.9Pr0.1InO 4 and is characterized by high values of proton conductivity at T < 450°C and pH2O = 2⋅10−2 atm.
EFFECT: increased proton conductivity of the material.
