Abstract
A hydrogen tank, preferably a tank for storing liquid hydrogen at low pressure in cryogenic condition, includes at least one gaseous hydrogen capture system. The system is provided with absorbent fillers configured to capture the gaseous hydrogen, the absorbent fillers being linked to at least a part of a wall of the tank, and/or to a skin arranged on an outer face of the tank, and/or to an outer jacket intended to implement an auxiliary function. The system has a reduced weight and is able to retain and store gaseous hydrogen which could escape from the tank so as to prevent it from being given off into the environment of the tank. The captured gaseous hydrogen is able to be restored later by the system.
