Embodiment Construction

[0019] In this case, FIG. 1 shows a schematic diagram of a hydrogen filling station. The filling station has a storage device S for storing liquid hydrogen and usually has a capacity of up to 1000 liters of liquid hydrogen - this corresponds to about 786 Nm 3 .

[0020] Furthermore, two delivery units or distributors G and F are provided, via which gaseous hydrogen (discharge unit G) and liquid hydrogen (discharge unit F) can be delivered to the vehicle to be filled.

[0021] The delivery of liquid hydrogen from the storage device S to the delivery unit F takes place via line sections 1 and 2 in which (corresponding to the advantageous configuration of the filling station according to the invention) a suitable cryopump P can be arranged.

[0022] An evaporator E, a cryogenic compressor V, a heater C and an intermediate storage device Z are connected upstream of the gaseous hydrogen discharge unit G in the direction of flow. The evaporator E and / or the heater C are preferably...

Abstract

A service station, in particular a hydrogen service station for filling a motor vehicle with a gaseous and / or a liquid medium, in particular with gaseous or liquid hydrogen, is disclosed. The station includes a) a reservoir for storing a liquid medium, b) a liquid medium dispensing unit which is supplied with the liquid medium from the reservoir, c) a compressor, an evaporator, a heating system, and an intermediate reservoir for intermediate storage of a compressed gaseous medium, d) a gaseous medium dispensing unit mounted downstream of the intermediate reservoir, e) a fuel cell which is supplied by the gaseous medium coming from the reservoir and / or the intermediate reservoir and supplies power to the compressor, and f) a control unit which is powered by the fuel cell and used for controlling the compressor, the gaseous medium dispensing unit and / or the liquid medium dispensing unit.

Description

technical field [0001] The invention relates to a filling station, in particular a hydrogen filling station, for filling a vehicle with a gaseous and / or liquid medium, in particular gaseous and / or liquid hydrogen. Background technique [0002] The term "vehicle" is to be understood hereinafter to mean all conceivable types of means of transport, such as passenger cars, trucks, buses, power machines, locomotives, etc., which are filled with gaseous and / or liquid media. [0003] Until now, filling stations of this type were usually fixed in location, dependent on external energy and not environmentally friendly. [0004] However, mobile filling stations for liquid and / or gaseous hydrogen are required precisely in the demonstration and introduction phase of the use of hydrogen as energy storage for vehicles. [0005] The mobile refueling of vehicles running on hydrogen has hitherto been carried out by transporting the hydrogen either in liquid form or under pressure by means o...
