A heat exchange structure is provided, including a primary face provided with non-through holes formed in said face, the inner surface of the holes and the surface of said primary face outside the holes being covered with nanoparticles, the inside of the holes having a non-wettability property relative to a given liquid and the surface of the face between the holes having a wettability property relative to the liquid.

Heat exchange structure and cooling device comprising such a structure

The tank is of the type including a container () for housing hydrogen, and metallic hydride placed inside the container. According to one aspect of the invention, it includes at least one solid body () formed of a compacted material including metallic hydride and a matrix. Application in particular for tanks for internal combustion engines or for fuel cells, in particular for motor vehicles, as well as for any stationary or mobile application using hydrogen.

Hydrogen storage tank

The invention relates to a safe hydrogen-storing tank that is easy to manufacture and enables the quick kinetic absorption of hydrogen, which reduces the variations in volume and has a low cost in terms of material and energy. The invention has the aim of providing a tank for storing hydrogen, including a hydrogen inlet () and a hydrogen outlet () in fluid communication with at least one solid body (-) capable of the exothermal absorption and endothermal desorption of hydrogen, wherein said at least one solid body (-) is made of a compacted material containing light metal hydride and a heat-conducting matrix, and wherein said at least one solid body (-) is in heat-transfer relation with at least one heat recovery material () free from salt or molten-salt compounds and capable of absorbing the heat generated by the hydrogen absorption and of releasing said absorbed heat so as to provide heat for hydrogen desorption.
