Replaceable cartridge for liquid hydrogen

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.

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.   
     
     
         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.   
     
     
         6 . The method of  claim 2 , wherein the consumer system is in an aircraft. 
     
     
         7 . The method of  claim 4 , wherein the consumer is in an aircraft system.
