METHOD OF LOW TEMPERATURE APPLICATION OF LOW RESISTANCE CATALYTICALLY ACTIVE COATING ON CONTACT LAYERS OF BIPOLAR PLATE IN CATHODE CAVITY OF HARD OXIDE FUEL ELEMENT Russian patent published in 2008 - IPC H01M8/12 

Abstract RU 2335830 C1

FIELD: technological processes; electricity.

SUBSTANCE: coating is applied on elastic elements with high-frequency magnetron sputtering from catalytically active and highly-electroconductive oxide-metal materials YSZ+Pt+V or YSZ+Ag. High-frequency magnetron sputtering of oxide-metal material YSZ+Pt+V is performed in mixture of inertial gas and oxygen with angle of elastic elements incline to the axis of bundle by 60° at continuous rotation of elastic elements around discharge axis in one direction, and high-frequency magnetron sputtering of oxide-metal material YSZ+Ag is performed in inertial gas. Position of elastic elements during sputtering is fixed with spot welding.

EFFECT: increase of output characteristics and resource of medium and low temperature hard oxide fuel elements.
