ABSTRACT:
A process for the reversible storage of hydrogen, comprising bringing into contact an alloy of magnesium and palladium with the gaseous hydrogen leading to the formation of hydride or corresponding hydrides, comprises the use of a balanced system correspondingto the formula:in-line-formulae description="In-line Formulae" end="lead"?MgxPdMgxPdHnin-line-formulae description="In-line Formulae" end="tail"?in which atomic ratio x takes on a value of 3 to 6, and n is the number of hydrogen atoms corresponding to the stoichiometry of the hydride or hydrides formedor to the formula:in-line-formulae description="In-line Formulae" end="lead"?MgxPdMg2PdH4+Mgx-2Hnin-line-formulae description="In-line Formulae" end="tail"?in which the atomic ratio x takes on a value of 7 to 9, and n is the number of hydrogen atoms corresponding to the stoichiometry of the hydride or hydrides formed.
