Abstract

A replaceable cartridge for coupling to a consumer or to a filling station, wherein the replaceable cartridge comprises at least one disconnectable connection coupling for connection to the consumer or the filling station. Furthermore, the replaceable cartridge comprises a tank for holding liquid hydrogen.

Claims

1. A method for handling a replaceable cartridge for coupling to a consumer system or to a filling station, the replaceable cartridge comprising at least one disconnectable connection coupling for connection to the consumer system or to the filling station and a tank for receiving liquid hydrogen, the method comprising the steps:

arranging or connecting the liquid hydrogen filled replaceable cartridge to a consumer system in an aircraft; and

removing the replaceable cartridge when it is detected that a fill level of the replaceable cartridge has fallen below a preset value.

2. A method for handling or keeping a replaceable cartridge for coupling to a consumer system or to a filling station, the replaceable cartridge comprising at least one disconnectable connection coupling for connection to the consumer system or to the filling station and a tank for receiving liquid hydrogen, the method comprising the steps:

connecting the liquid hydrogen filled replaceable cartridge to the consumer system or to the filling station; and

automatically detecting by way of an encoding on the disconnectable connection coupling, information relating to the type of the replaceable cartridge so connected.

3. The method for handling a replaceable cartridge of claim 2, wherein the encoded information relating to the type of the connected replaceable cartridge comprises at least one of:

a type of filling;

a temperature of the stored hydrogen;

an average supply quantity of gaseous hydrogen to the consumer;

a fill pressure;

a shape;

a tank size;

a maximum removal quantity;

an application;

a maximum heat infeed;

a maximum operating pressure;

a nominal volume.

6. The method of claim 2, wherein the consumer system is in an aircraft.

4. A method for handling a replaceable cartridge for coupling to a consumer or to a filling station, the replaceable cartridge comprising at least one disconnectable connection coupling for connection to the consumer or to the filling station and a tank for receiving liquid hydrogen, the method comprising the steps of:

entrapping a catalyst in a space defined by a protective cap arranged above the disconnectable connection coupling;

utilizing, by way of the entrapped catalyst, any hydrogen that evaporates from the connection coupling into said space.

5. The method for handling a replaceable cartridge of claim 4, wherein

the utilizing of the catalyst comprises converting of the evaporated hydrogen into water to prevent any accumulation of evaporating hydrogen.

7. The method of claim 4, wherein the consumer is in an aircraft system.
