Title (EN) HYDROGEN GAS SENSOR
(FR) CAPTEUR D'HYDROGÈNE GAZEUX
(JA) 水素ガスセンサ
Abstract:
(EN) Disclosed is a hydrogen gas sensor provided with a substrate, a hydrogen detection film provided on the substrate, and a pair of electrodes provided to the hydrogen detection film. The hydrogen detection film includes a metal oxide and a catalyst. In a Raman spectrum obtained by measuring microscopic Raman scattering in the hydrogen detection film, the ratio of the peak intensity of double bonds between metal atoms and oxygen atoms in the metal oxide with respect to the maximum peak intensity of single bonds between the metal atoms and the oxygen atoms is 0.19 or less.
(FR) L'invention concerne un capteur d'hydrogène gazeux ayant un substrat, d'un film de détection d'hydrogène disposé sur le substrat, et une paire d'électrodes disposées sur le film de détection d'hydrogène. Le film de détection d'hydrogène comprend un oxyde métallique et un catalyseur. Dans un spectre Raman obtenu par mesure de diffusion Raman microscopique dans le film de détection d'hydrogène, le rapport de l'intensité de crête de liaisons doubles entre des atomes de métal et des atomes d'oxygène dans l'oxyde métallique par rapport à l'intensité de crête maximale de liaisons simples entre l'oxyde métallique et les atomes d'oxygène est 0,19 ou moins.
(JA) 基板と、基板上に設けられる水素検知膜と、水素検知膜に設けられる一対の電極とを備える水素ガスセンサが開示されている。水素検知膜は金属酸化物及び触媒を含み、水素検知膜についての顕微ラマン散乱測定を行って得られるラマンスペクトルにおいて、金属酸化物における金属原子及び酸素原子の一重結合の最大ピーク強度に対する金属原子及び酸素原子の二重結合のピーク強度の比が0.19以下である。
