Hydrogen tank for supplying hydrogen to a fuel cell, comprises a material such as a metal hydride capable of absorbing hydrogen via natural chemical bonds, and a compressible material for covering a part of internal walls of the tank
The hydrogen tank (1) comprises a material such as a metal hydride capable of absorbing hydrogen via natural chemical bonds (4), and a compressible material (3) for covering a part of internal walls of the tank. The walls of reservoir are made of polymer. The compressible material includes elastomers and hollow microspheres (10-90%) made of polymers or glass, and is present in the form of cavities inside the tank. The hollow microspheres have a diameter of 100-1000 mu m.

The hollow microspheres have a diameter of 100-1000 mu m. The metal hydride is expressed as ABn, where A represents a metallic element with high affinity for hydrogen and comprising an alkaline metal, an alkaline earth metal, a primary transition metal, a rare earth metal or an actinide, B denotes an element of low affinity for hydrogen and consisting of a middle or final transition metal, or an element p.
