NOVELTY - A solid-state hydrogen storage material comprises: a porous matrix material having atoms of a first element capable of bonding with hydrogen atom per atom of first element; hydrogen atoms molecularly bonded to atoms of first element; and atoms of a second element capable of molecularly bonding to atoms of first element and hydrogen atoms. The atoms of second element is bonded to atoms of first element having bond sites for more than one hydrogen atom, as a result at lower bond energies than the bond sites of atoms of first element to which a fewer number of hydrogen atoms are bonded.    USE - As a solid-state hydrogen storage material for delivering hydrogen to a power-generating device coupled to a power-consuming device, i.e. a fuel cell, vehicles, stationary power systems, or consumer electronic devices (claimed).    ADVANTAGE - The solid-state hydrogen storage material is rechargeable and capable of achieving a full or nearly-full recharge, thus reducing the cost of owning and operating a hydrogen storage system and making the use of such storage systems practical for use in a wide variety of applications, including powering fuel cells for vehicles, stationary power systems, and consumer electronics, and non-power applications including chemical production. The method employs a catalyst to inhibit reforming of silicon dangling bonds after dehydrogenation that result in silicon-to-silicon bonds and reduce the number of bond sites available to participate in hydrogen storage. As such, the catalyst is able to preserve bond sites for hydrogen bonding during subsequent rehydrogenation. Through the use of a catalyst in this manner, a solid-state hydrogen storage material can be potentially made at lower cost and weight and processed and operated at lower temperatures compared to the prior art. As such, the method is capable of significantly increasing the practicality, functionality and economics of solid-state hydrogen storage systems. Furthermore, recharging can be performed without significantly reducing the mass of the storage media. As a result, multiple recharges can be performed that achieve near-complete recharging of hydrogen, for example, at least 90% and more preferably at least 99.98% relative to the original charge, with charge levels believed to be reduced only by contaminants such as dissolved oxygen or other impurities.    DETAILED DESCRIPTION - A solid-state hydrogen storage material comprises: a porous matrix material containing atoms of a first element capable of bonding with more than one hydrogen atom per atom of the first element, the atoms of the first element is molecularly arranged within the porous matrix material so that different atoms of the first element have bond sites available for different numbers of hydrogen atoms at correspondingly different levels of bonding energy; hydrogen atoms molecularly bonded to atoms of the first element, some atoms of the first element having more hydrogen atoms bonded to it than other atoms of the first element; and atoms of a second element capable of molecularly bonding to atoms of the first element and the hydrogen atoms, the atoms of the second element is bonded to those atoms of the first element having bond sites for more than one hydrogen atom and as a consequence at lower bond energies than the bond sites of those atoms of the first element to which a fewer number of hydrogen atoms are bonded. An INDEPENDENT CLAIM is included for forming a solid-state hydrogen storage material involving: forming a porous matrix material to comprise atoms of the first element and hydrogen atoms, the atoms of the first element is molecularly arranged within the porous matrix material so that different atoms of the first element are bonded to different numbers of hydrogen atoms at correspondingly different levels of bonding energy; removing at least some of the hydrogen atoms bonded to the atoms of the first element at the lowest bond energies without removing the hydrogen atoms bonded to the atoms of the first material at higher bond energies; and molecularly bonding atoms of a second element to the atoms of the first element from which the hydrogen atoms were removed.
