摘要

A process is provided for optimizing the storage capacity, based on weight, of a hydrogen storage device containing a hydride-forming alloy. A corresponding hydrogen storage device is also provided wherein the storage device is designed to operate under a pressure of 100 to 300 bars, and the weight of hydride-forming alloy contained within the device is about 0.8 to 2 kg of hydride-forming alloy per liter of internal volume. As an added benefit attendant this process and device, the hydrogen gas stored in the device is purified thereby.
