A hydrogen storage tank includes a shell of longitudinal axis, a hydrogen supply and collection duct, and a stack of a plurality of divider elements. Each divider element forms a bottom accepting a hydrogen storage material. The largest transverse dimension of the divider elements is less than the largest transverse dimension of the internal volume of the shell, and the tank includes a plurality of seals in the space formed between the divider element and the shell as a result of the difference in largest transverse dimension.

Hydrogen storage tank comprising a plurality of seals

A hydrogen storage material tank including a shell along a longitudinal axis, a hydrogen supply and collection duct along a longitudinal axis, a stack of plural cups around the duct, wherein each cup includes a base perpendicular to the longitudinal axis, a passage allowing installation of the cup around the duct, an outer wall perpendicular to the base, in contact with the shell and an inner wall perpendicular to the base and in contact with the duct, wherein each cup is force-fitted on the duct and each cup includes a mechanism allowing mutual engagement of the cups in one another by mechanical deformation of free ends of the outer walls of the cups.

Hydrogen storage tank comprising metal hydrides produced through simplified manufacture and storage device comprising at least such a tank

A tank for storing hydrogen through absorption into a material, the tank having a longitudinal axis and including an outer enclosure and an inner structure having a longitudinal axis, including a plurality of stages and a heat exchange system within the inner structure, each stage including a lower bottom, an upper bottom, longitudinal partition walls, and transverse partition walls. The partition walls form with the lower and upper bottoms compartments for receiving the hydrogen storage material. The upper bottom and/or the upper bottom and the transverse partition walls or longitudinal partition walls are made as a single piece.

Hydrogen storage tank with metal hydrides

A hydrogen storage tank by absorption into a hydrogen storage material, the tank having a longitudinal axis and including an enclosure and an inner structure provided within the enclosure. The inner structure includes a plurality of stages and a heat exchange system within the inner structure, each stage including a plurality of compartments distributed into a plurality of rows directed along the longitudinal direction, each compartment having a semi-cylindrical shape, and each compartment containing a hydrogen storage material, wherein the material has been introduced through the opening.
