Abstract
A hydrogen storage system comprises a hydrogen tank and a system for controlling hydrogen evaporation in the hydrogen tank. This control system comprises a hydrogen discharge pipe connected to the hydrogen tank, on the one hand, and to a controllable valve, on the other hand, as well as a processing unit configured to control the valve as a function of the pressure in the tank. The hydrogen storage system further comprises a fuel cell permanently connected to the hydrogen tank and the processing unit being electrically powered by the fuel cell.
Claims11
An aircraft comprising:
- a hydrogen storage system comprising a hydrogen tank and a control system for controlling hydrogen evaporation in the hydrogen tank, the control system comprising:
- a hydrogen discharge pipe connected at one end to the hydrogen tank and to a controllable valve at a second end;
- a controller configured to control the valve as a function of a pressure value in the tank, to ensure that the pressure value inside the hydrogen tank does not exceed a first predetermined pressure threshold;
- a fuel cell permanently and unbrokenly fluidically coupled to the hydrogen tank separately from the hydrogen discharge pipe to permanently generate electricity even when the aircraft is parked on ground as long as hydrogen remains in the tank, wherein the controller is electrically powered by the fuel cell.
