Abstract:
1. The process of making a hydrogen storage apparatus comprising the steps of: forming a hollow glass microsphere having an extractable phase; removing said extractable phase, thereby providing a porous wall hollow glass microsphere said porous wall defining a plurality of pores which provide communication between an interior and an exterior of the porous wall hollow glass microsphere, said porous wall hollow glass microspheres having a diameter of between about 1.0 to about 200 microns, a density of about 1.0 to about 2.0 gm/cc, and an average pore size in arrange from about 10 to about 1,000 angstroms; introducing through said plurality of pores a hydrogen storage material into an interior of said porous wall hollow glass microsphere via a pressure differential; heating said porous wall hollow glass microsphere containing said hydrogen storage material to a temperature of about 1000° C. and thereby decreasing the porosity of the porous wall hollow glass microspheres, said decrease in porosity excluding the passage of gaseous poisons into the interior of said porous wall hollow glass microsphere; wherein said hydrogen storage apparatus can reversibly release and store hydrogen said hydrogen entering and exiting said storage apparatus through said plurality of pores.
