Document Type and Number:
WIPO Patent Application WO/2016/143385
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: a hydrogen gas detecting member exhibiting large variations in light transmittance or color according to hydrogen gas concentration and having a high detection sensitivity; a method for manufacturing the same; and a hydrogen gas detecting system having the same. The problem is solved by a hydrogen gas detecting member in which the light absorption characteristics vary with changes in hydrogen gas concentration, the hydrogen gas detecting member including a cerium oxide-containing layer, a tungsten oxide-containing layer, and a catalytic metal element-containing layer, wherein the cerium oxide-containing layer is disposed adjacent to the tungsten oxide-containing layer, and the catalytic metal element-containing layer is disposed on the reverse side of the surface of the tungsten oxide-containing layer facing the cerium oxide-containing layer.
