The invention relates to a method for preparing to refuel a tank in a vehicle with hydrogen, for which purpose the tank pressure is lowered in preparation for driving to a filling station, wherein the filling station is informed of the pending refueling. The method according to the invention is characterized in that the refueling takes place with liquid hydrogen, wherein the maximum achievable pressure level of the tank during refueling, the expected pressure level of the tank when the filling station is reached, and the expected refueling quantity are transmitted to the filling station.

Method for preparing to refuel a vehicle

A device that stores a low molecular gas, such as hydrogen (H), under high pressure includes having an inner shell and at least one outer sleeve surrounding the inner shell. The region between the inner shell and the outer sleeve is connected via at least one valve with a backflow prevention capability to the region surrounded by the inner shell. The valve is thereby formed so that low molecular gas which has diffused through the inner shell can flow back into the inner shell when there are suitable pressure conditions.
