Abstract
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.
