  • Publication number: 20150093667
    Abstract: A hydrogen cartridge with a dispensing end, said cartridge having unique identification associated therewith is disclosed, said cartridge providing a supply of hydrogen and being removably fitted to a host device. Prior to use in said host device, the unique identifier is input into a communications device which, through a network, contacts a secure database with records of authentic unique identifiers. Said secure database may require verification of a user and/or a communication device prior to granting access. The host device also has a communications link whereby one of the database and the communications device may provide authorization to a host device, including but not limited to a controller, to utilize the hydrogen in the canister associated with a specific unique identifier.

  • Patent number: 7954519
    Abstract: Safe storage of volatile compounds or elements is provided by utilizing storage configurations that take advantage of the diffusibility and release characteristics of cell-based materials, such as foam materials. Such configurations may provide storage of hazardous, liquefied gases in closed-cell foam material. Release of gas/liquid from the foam is restricted by the need for the gas to diffuse through the closed cells. Because rapid release is prevented, storage safety is greatly improved.
