DEVICE FOR STORING HYDROGEN
The invention relates to a device (100) for storing hydrogen, comprising: a first material (111) for storing hydrogen by sorption, a second material (112, 121) for the reversible storage of hydrogen by sorption, and a chamber (110) containing the first material (111), in which, at the same temperature and the same hydrogen loading rate, the first material has a desorption equilibrium pressure that is strictly higher than that of the second material, and the second material is in fluid communication with the first material, said fluid communication being direct or by means of fluid communication means, such that the second material allows the pressure in the chamber to be limited.
