GASOCHROMIC THIN FILM FOR HYDROGEN SENSOR WITH IMPROVED DURABILITY AND HYDROGEN SENSOR CONTAINING THE SAME

摘要

The present invention provides a thin film for a hydrogen sensor comprising a catalytic layer which comprises (a) a gasochromic layer; and (b) palladium (Pb) and platinum (Pt) deposited on the gasochromic layer and a hydrogen sensor having the same. The hydrogen sensor of the present invention represents not only much more improved durability having its reactivity in above 1000 cycles but also much more enhanced sensitivity. The hydrogen sensor of this invention for safe utilization of hydrogen energy may be used in a photosensor for sensing a hydrogen leakage, and be also promising in its marketability in the senses that the hydrogen energy as an alternative powerful energy source is widely used.
