ABSTRACT:
A process for the reversible storage of hydrogen, comprising bringing an alloy of alkaline metal and silicon into contact with gaseous hydrogen leading to the formation of the hydride or corresponding hydrides, comprises the use of at least one balanced system that correspondsto the formula:in-line-formulae description="In-line Formulae" end="lead"?MXMSi MXMSiHnin-line-formulae description="In-line Formulae" end="tail"? where M is selected from among Li, Na, or K and in which atomic ratios XMtake on the following values:in-line-formulae description="In-line Formulae" end="lead"?XLi=1in-line-formulae description="In-line Formulae" end="tail"?in-line-formulae description="In-line Formulae" end="lead"?1≦XNa≦3in-line-formulae description="In-line Formulae" end="tail"?in-line-formulae description="In-line Formulae" end="lead"?1≦XK≦2in-line-formulae description="In-line Formulae" end="tail"? n is the number of hydrogen atoms corresponding to the stoichiometry of the hydride or formed hydrides.or to the formulain-line-formulae description="In-line Formulae" end="lead"?MSiXSi MSiXSiH2XSi+1in-line-formulae description="In-line Formulae" end="tail"? where M is selected from among Li, Na, or K and in which the atomic ratio XSi=Si/M takes on a value of 1 to 4.
