HYDROGEN DETECTOR Russian patent published in 2014 - IPC G01N27/14 

FIELD: measurement equipment.

SUBSTANCE: invention relates to analysis of materials, in particular, for detection of hydrogen content, and may be used in manufacturing of hydrogen gas analysers in space engineering, motor industry, chemical industry, etc. Substance of the invention: a resistive sensor of hydrogen concentration is proposed, comprising a hydrogen-sensitive element made in the form of a thin-film resistor, comprising in a material at least palladium oxide and a heating element that heats the hydrogen-sensitive element. The hydrogen-sensitive element may be made of silver-palladium resistive paste. The sensor may be made in accordance with a simple and cheap technology widely used in the industry.

EFFECT: creation of a miniature hydrogen detector to detect both atomic and molecular hydrogen, making it possible to perform qualitative and quantitative measurements.
