Claims10
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.
