▎ 摘　　要

NOVELTY - The installation (1) comprises a hydrogen reservoir (10) and a hydrogen distribution pipe (20a,20b), where a surface of the hydrogen tank or a hydrogen distribution pipe being covered with a two-dimensional material. The two-dimensional material is mixed with a polydopamine type polymer. The surface corresponds to an internal surface of the hydrogen reservoir or of a hydrogen distribution pipe. The two-dimensional material is chosen from the following two-dimensional materials, graphene, graphene oxide, and hexagonal boron nitride. USE - Installation for distributing hydrogen between a hydrogen tank and a hydrogen consumer, such as an engine or a fuel cell, used in aircraft, watercraft, or hybrid vehicle using a hdrogen distribution pipe (all claimed). ADVANTAGE - The surface covered by the two-dimensional material has the advantage of being impervious to the passage of hydrogen, which makes it possible to prevent hydrogen leaks through the walls of the hydrogen tank or of the distribution pipes. The polydopamine type polymer has high adhesion properties on a surface to which it is applied. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of an installation.
