FIELD: electricity.
SUBSTANCE: invention can be used in industrial production of batteries of high-temperature solid oxide fuel cells. Method of producing nanodispersed powder of molybdenum dioxide involves electrochemical deposition. Electrolysis is carried out at constant current density of 400–800 A/m2 for 5–30 minutes using a chemically stable cathode in electrolyte with 15–80 g/l of ammonium heptamolybdate, 10–30 g/l of ammonium chloride at pH 8.5–10.0. Dehydration of powder obtained by electrolysis is carried out by heating at temperature of 150 °C for 30 minutes.
EFFECT: invention enables to obtain material with specific surface area of 10–25 m2/g for use as material of anode of high-temperature solid-oxide fuel cell using liquid hydrocarbons as fuel.
