A hydrogen-based propulsion system is provided for storing hydrogen feed gas which evaporates over time from a storage vessel containing liquid hydrogen as a fuel. In particular, this system enables the evaporated hydrogen feed gas to be stored for later use in the propulsion unit and also provides a system for enabling the stored hydrogen gas to be cooled by evaporated hydrogen feed gas in transit to the propulsion unit.

What is claimed is: 1. A hydrogen supply system for a fuel cell, comprising: a liquid hydrogen storage tank; a purge container in communication with the liquid hydrogen storage tank, said purge container comprising an outer tank in communication with said liquid hydrogen storage tank and an inner tank disposed within said outer tank and in communication with said liquid hydrogen storage tank, each of said inner and outer tanks of said purge container having an outlet passage. 2. The system of claim 1, wherein the inner tank is disposed within the first tank to enable the fluid in the outer tank to surround the second tank. 3. The system of claim 2, further comprising: a controller operable to generate a signal based upon input from at least one sensor; a first valve in communication with the outer tank, the first valve operable by the controller to enable the outer tank to receive hydrogen vapor from said liquid hydrogen storage tank; and a second valve in communication with the inner tank, the second valve operable to enable the inner tank to receive said hydrogen vapor from said liquid storage tank. 4. The system of claim 3, wherein said controller is in communication with a bypass valve disposed in a bypass passage that communicates with said liquid hydrogen storage tank and not said purge container, and said controller is operable to cause the bypass valve to open. 5. The system of claim 4, wherein the purge container further comprises a source of thermal energy to heat the purge container in response to a control signal from said controller. 6. The system of claim 1, wherein said inner tank of said purge container further comprises a material selected from the group consisting of high surface materials such as super-activated carbon, zeolites, metal-organic compounds or combinations thereof. 7. A hydrogen-based propulsion system for a vehicle, the propulsion system comprising: a propulsion unit operable to provide energy to the vehicle; and a hydrogen supply system connected to said propulsion unit and including a liquid hydrogen storage tank and a purge container in communication with the liquid hydrogen storage tank, said purge container comprising an outer tank in communication with said liquid hydrogen storage tank and an inner tank disposed within said outer tank and in communication with said liquid hydrogen storage tank, each of said inner and outer tanks of said purge container having an outlet passage connected to said propulsion unit. 8. The system of claim 7, wherein said inner tank is disposed within said outer tank to enable a reactant in the outer tank to surround the inner tank. 9. The system of claim 8, further comprising: a controller operable to generate a signal based upon input from at least one sensor; a first valve in communication with the outer tank, the first valve operable by the controller to enable the outer tank to receive hydrogen vapor from said liquid hydrogen storage tank; and a second valve in communication with the inner tank, the second valve operable to enable the inner tank to receive said hydrogen vapor from said liquid storage tank. 10. The system of claim 9, wherein said controller is in communication with a bypass valve disposed in a bypass passage that communicates with said liquid hydrogen storage tank and not said purge container, and said controller is operable to cause the bypass valve to open. 11. The system of claim 10, wherein the purge container further comprises a source of thermal energy to heat the purge container in response to a control signal from said controller. 12. The system of claim 11, wherein said inner tank of said purge container further comprises a material selected from the group consisting of high surface materials such as super-activated carbon, zeolithe, metal-organic compounds or combinations thereof.
