Abstract
A power unit, a fuel cartridge, and a fuel cell system having the power unit and the fuel cartridge. The power unit includes a coupling unit to couple with the fuel cartridge. The coupling unit includes a nozzle that receives fuel supplied from the fuel cartridge, a selection key to selectively mate with the fuel cartridge, and an outer unit surrounding the nozzle. An end of the nozzle is located between the selection key and an end of the outer unit.
Claims42
A power unit comprising a coupling unit to couple with a fuel cartridge, the coupling unit comprising:
- a nozzle to receive fuel from the fuel cartridge;
- an outer unit surrounding the nozzle;
- and
- a selection key disposed on the outer surface of the outer unit, to selectively mate with the fuel cartridge,
- wherein the position of the nozzle is lower than an end of the outer unit and higher than the selection key.
A fuel cartridge comprising a coupling unit to couple with a power unit having an outer unit, the coupling unit comprising an inner circumference unit to mate with the outer unit of the power unit, having a fuel supply path through which fuel is supplied from the cartridge to a nozzle the power unit, and a groove to accommodate a selection key of the power unit.
A fuel cell system comprising:
- a power unit comprising a first coupling unit;
- and
- a fuel cartridge to supply a fuel to the power unit, comprising a second coupling unit to couple with the first coupling unit, wherein,
- the first coupling unit comprises,
- a nozzle that receives the fuel supplied from the fuel cartridge,
- an outer unit that surrounds the nozzle, and
- a selection key disposed on the outer surface of the first coupling unit, to selectively mate with the fuel cartridge, and
- the second coupling unit comprises,
- a fuel supply path that supplies the fuel to the nozzle, and
- an inner circumference unit to mate with the outer unit, having a groove disposed therein to accommodate the selection key.
A fuel cell system comprising:
- a power unit comprising,
- a nozzle that receives a fuel, and
- a first poppet to open and close a fuel supply path at least partially defined by the nozzle and the first poppet and
- a fuel cartridge to couple with the power unit to supply the fuel to the power unit, comprising,
- the fuel supply path to supply the fuel to the nozzle;
- and
- a first exposure inducing unit to move the first poppet to open the fuel supply path, when the power unit and the fuel cartridge are coupled.
