Patent ID: 7810669

Claim:
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 to the filling station; and a tank for receiving liquid hydrogen, wherein the tank comprises an internal tank, an external tank, and a device for supplying heat to the internal tank, and wherein for storing liquid or partially liquefied hydrogen, the internal tank and the external tank are thermally decoupled by means of superinsulation, the superinsulation having a heat transfer coefficient selected so that, when the cartridge is in use, a desired amount of heat transfer from the environment at ambient temperature to the internal tank effects formation of desired amount of gaseous hydrogen commensurate with a non-zero consumption by the consumer of the so-formed gaseous hydrogen, such that the replaceable cartridge does not require any regulating devices for controlling the quantity of hydrogen delivered.
