Abstract
Systems and methods for producing a lightweight vacuum insulated vessel are provided herein. An exemplary vessel is of a non-radially symmetric shape and maintains vacuum pressure between two concentric containers (an inner container and outer container). The vacuum insulated vessel is made to withstand high temperatures in a furnace during manufacture. Further, the vessel may contain a fuel cartridge for a fuel cell system and be insulated to retain heat necessary for the fuel cartridge reactions.

A lightweight vacuum insulated vessel for reducing heat loss, the vessel comprising:
- a hollow inner can of a non-radially symmetric shape and being a long aspect ratio cylindrical shape, the inner can comprising sides and a bottom surface;
- a hollow outer can of a non-radially symmetric shape and being the long aspect ratio cylindrical shape placed around the inner can, the outer can comprising sides and a bottom surface;
- a cavity formed between the inner can and the outer can, the cavity maintained at vacuum pressure;
- a lid covering a top of the inner can;
- and
- a connecting ring covering a top of the cavity, wherein the lid and the connecting ring together cover an entire top surface of the vacuum insulated vessel;
- wherein the inner can further comprises at least two thermally insulated spherical standoffs attached to an outer side surface of the inner can, the at least two thermally insulated spherical standoffs protruding into the cavity and providing support to a side wall of the outer can.
