La présente invention concerne un réservoir pour le stockage d’hydrogène et la fourniture d’hydrogène gazeux à une pile à combustible, comprenant un conteneur d’hydrogène comprenant une entrée adaptée pour recevoir de l’hydrogène liquide (ou fluide), le conteneur d’hydrogène comprenant une sortie d’hydrogène gazeux, le réservoir comprend un conteneur de rétroaction, le conteneur de rétroaction comprenant une entrée d’hydrogène gazeux et une sortie d’hydrogène gazeux, le réservoir comprenant un chemin d’écoulement de l’hydrogène gazeux traversant le conteneur de rétroaction, le chemin d’écoulement étant au moins défini depuis l’intérieur du conteneur d’hydrogène jusqu’à la sortie d’hydrogène gazeux du conteneur de rétroaction.Une partie au moins du chemin d’écoulement est agencée dans le conteneur de rétroaction et étant formée au moins en partie par une paroi du conteneur d’hydrogène.

The present invention relates to a tank for storing hydrogen and supplying gaseous hydrogen to a fuel cell, comprising a hydrogen container comprising an inlet suitable for receiving liquid hydrogen, the hydrogen container comprising a hydrogen gas outlet, the tank comprising a feedback container, the feedback container comprising a hydrogen gas inlet and a hydrogen gas outlet, the tank comprising a hydrogen gas flow path passing through the feedback container from the inside of the hydrogen container to the hydrogen gas outlet of the feedback container. The fact that the tank is open suggests that there is a continuous gaseous discharge which begins as soon as the hydrogen container has been loaded with liquid hydrogen. The shell wall that covers the tank and has low or moderate thermal conductance, and allows for an environmental heat input which continuously propels the hydrogen gas along the flow path towards the hydrogen gas outlet. As a result, the open tank discharges most of its gaseous content for the desired duration as programmed for the vehicle type, preferably in less than 24 hours. Said open tank comprises a dam and lock system consisting of a series of plugs of porous material which are successively arranged over a whole section of the flow path, and staggering the decreasing pressures in the compartments in the direction of gas flow and enabling - internal pressures of less than 200 bar in all of the inner compartments, - the open tank (1) to be manufactured in malleable and varied forms (cylindrical, or flat and elongated and/or curved forms) that match the requirements of the vehicles into which they are inserted.
