초록

A hydrogen getter comprising a thin film having a layer of inert material, and a hydrogen reactive material disposed in or attached to the layer of inert material. The hydrogen reactive material may comprise palladium oxide powder, and the layer of inert material may comprise an epoxy resin. Various forms of the hydrogen reactive material may be used including porous composite, or a solid composite comprising a powder coated organic thin film, for example. An alternative gettering system that is operative in an oxygen environment uses a thin film of hydr...
