PROCESS FOR ACCUMULATING HYDROGEN

摘要

The present invention provides a hydrogen loaded solid substance comprising at least 10% w/w of hydrogen. The solid is polycrystalline heat steady substance with large interstructural area, made of carbon and transition metals, carbon and rare earth element, intermetalloid, and/or hydride thereof. Also provided by the invention is a process for loading such solid with hydrogen. The process includes exposing the solid substance to hydrogen pressure of at least 500 Atm at a temperature of at least 1000°C and then cooling at a rate of at least 10°C/sec.
