Reversibles Wasserstoffspeicherelement und Verfahren zu seiner Befuellung und Entleerung

WO 2009018821 A2 UPAB: 20090311 NOVELTY - The reversible hydrogen storage element comprises an outer shell, which exhibits an increasing permeability for hydrogen at temperatures above 20 degrees C, is made of a metal or a metal alloy and has a shell thickness of 20 mu m. The outer diameter of the hollow sphere is 3 mm. The shell of the hollow sphere is formed from two layers. The outer layer has a layer thickness smaller than a layer formed under it. The hollow sphere has strength of 10 MPa. The storage element has a gravimetric storage density of above 1 wt.%. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for filling and emptying the hydrogen storage elements. USE - Used as a reversible hydrogen storage element. ADVANTAGE - The reversible hydrogen storage element has increased gravimetric storage density.
