Title:
HYDROGEN GAS SENSOR
Document Type and Number:
WIPO Patent Application WO/2022/203370
Kind Code:
A1
Abstract:
The present invention relates to a hydrogen gas sensor, and specifically, to a hydrogen gas sensor which has a fast response rate and high selectivity to hydrogen gas even without an additional heating means, and which is capable of sensing even a low concentration of hydrogen gas with high sensitivity. The hydrogen gas sensor of the present invention comprises: a tin oxide layer; a first electrode and a second electrode, spaced apart from each other on the tin oxide layer; a palladium nanoparticle layer positioned in a spaced-apart region between the first electrode and the second electrode; and a polymer layer positioned on the palladium nanoparticle layer and including an acrylate-based polymer.
