The gas-tight container has a container wall (12) of thermoplastic plastic material, with at least one diffusion barrier including metal hydride bounding the interior (20) of the container. The oxygen may be stored in a metal hydride with a desorption temperature lower than that of the metal hydride in the diffusion barrier. Die vorliegende Erfindung betrifft gasdichte Lager- und/oder Transportbehälter für niedermolekulare Füllmedien, insbesondere für Wasserstoff mit einer Behälterwandung, die einen thermoplastischen Kunststoff und wenigstens eine Diffusionssperre umfasst. Die Diffusionssperre umfasst ein Metallhydrid.
