Abstract:
1. An apparatus for producing hydrogen gas by mechanical scraping of a surface of an aluminum-containing material, in the presence of an aqueous medium, the apparatus comprising: (a) a reaction chamber having a discharge port, and adapted to sealably contain the aqueous medium; (b) an aluminum-containing workpiece having a working surface; (c) a scraping mechanism having at least one scraping element adapted to contact said working surface, and (d) an aqueous medium; said aluminum-containing workpiece, said scraping element, and said aqueous medium disposed within said chamber, said chamber adapted to be substantially sealed with respect to an external environment, said chamber further adapted whereby, during contacting of the aqueous medium and said particles within said chamber, the hydrogen gas evolved is discharged through said discharge port, said surface and said scraping element adapted to move in a relative motion, said chamber including a flexible external wall, adapted to be flexed by a force external to said chamber, to achieve said relative motion, whereby, in a relaxed condition of said external wall, said scraping element is substantially stationary with respect to said working surface, and whereby, in an operating condition, said scraping element scrapes against said working surface to effect a liberation of aluminum-containing particles from said aluminum-containing workpiece.
