    • A container (12) is disposed within a vacuum insulation jacket which surrounds a vessel or pipe which contains or through which flows a hydrogen containing medium. The con­tainer holds oxygen under pressure or holds a material which liberates oxygen when exposed to heat and/or reacts with water to liberate oxygen. The container is sealed by means of a membrane (13) of palladium or palladium alloy. A water absorbing material (16) is disposed inside the container. The palladium membrane is thus exposed on its first side facing the interior of the container to a region of relatively high oxygen pressure produced by the oxygen inside the container and low hydrogen partial pressure inside the container, and is exposed on its other side to the vacuum (low oxygen pres­sure, and higher hydrogen partial pressure as a result of the outgassing or permeation of hydrogen from the medium in contact with the vacuum chamber walls). The palladium acts as a catalyst for the combination of hydrogen and oxygen to form water when hydrogen flows from the vacuum jacket into the container following the hydrogen pressure gradient. The water thus formed is absorbed inside the container using a suitable water absorber, such as a molecular sieve. The method of using the device includes placing it within a vac­uum chamber or between two concentrically arranged pipes constituting a vacuum chamber so that the palladium or pal­ladium alloy membrane is in thermal communication with a high temperature surface, such as the surface of the wall of the pipe containing steam or a heat transfer fluid.
