GAS STORAGE PRESSURE VESSEL COMPRISING PHASE CHANGING MATERIAL

摘要

The present invention provides a device that minimizes or eliminates under-filling of a pressure vessel by integrating phase change material (PCM) within one or multiple component of the pressure vessel. In one particular embodiment, the inner surface of the pressure vessel comprises a PCM. During a gas-filling process, PCM reduces the rate and/or the amount of temperature increase. Reduction of the temperature increase in the pressure vessel increases the amount of gas filled during a gas-filling process.

主权项

1. A gas storage vessel comprising:
a gas outlet port configured to be connected to a pressure regulator and for discharging a gas stored within said vessel; a gas inlet port configured for charging said vessel with a gas; and an inner surface,wherein said inner surface of said vessel comprises a phase-change material configured to reduce the temperature change within the interior of said vessel during a gas filling process.
