Abstract
The invention provides a hydrogen pump for vacuum insulation jackets for a vessel or a pipe which holds or through which flows a hydrogen-containing medium at temperatures such that hydrogen permeates into the jacket, comprising a palladium or palladium alloy membrane exposed on one side to an oxidizing atmosphere and on its other side to the evacuated space within the jacket, wherein the membrane enables the flow of the hydrogen from the evacuated space through the membrane into the oxidizing atmosphere.
