Abstract: An arrangement for the elimination or removal of hydrogen from a hydrogenntaining gas mixture through the intermediary of foils which are fastened within a closable container, wherein the material of the foils produces an elimination of hydrogen, whereby the foils are so arranged at such spacings with respect to each other as to form interspaces between the foils which can be streamed through by the gas mixture. At least one supporting member having the foils adhering thereto is arranged within the container in such a manner that the foils will extend into the surroundings upon opening of the container. Especially suitable for this purpose are spirally-wound supporting members which will extend out of the container under the effect of gravity or under the action of a mechanical spring force, and in this manner provide a direct contact between the effective foil material and the explosively dangerous gas mixture.
