HYDROGEN SENSING APPARATUS AND METHOD FOR PRODUCING SENSOR THEREOF

摘要

PURPOSE: A hydrogen detecting device and a sensor manufacturing method for the same are provided to transfer lights using an optical fiber even though a measuring location and a place where controlling the same are spaced from each other so that signal intensity is not diminished. CONSTITUTION: A hydrogen detecting device comprises a thin film, a catalytic layer(13), a substrate(11), and an optical fiber. The thing film is composed of gas coloring materials in which color is changed when being exposed to hydrogen. The catalytic layer evaporates by alloying Pd and Ni on the thin film. The substrate supports the thin film. The optical fiber transfers lights to the thin film and the lights reflected from the thin film to a reverse direction.
