Abstract
Official abstract text for this publication.
A method and apparatus for generating hydrogen gas by reacting a nanogalvanic alloy with water vapor. The apparatus comprises a water vapor source for supplying water vapor to a reaction chamber containing a nanogalvanic alloy. The nanogalvanic alloy reacts with the water vapor to produce hydrogen.
First claim
Opening claim text (preview).
1 . Apparatus for generating hydrogen comprising: a water vapor source for supplying water vapor; a reaction chamber, coupled to the water vapor source, containing a nanogalvanic alloy that reacts with the water vapor to generate hydrogen. 2 . The apparatus of claim 1 further comprising a desiccant chamber coupled to the reaction chamber for removing water vapor from the hydrogen. 3 . The apparatus of claim 2 wherein the desiccant chamber comprises a desiccant comprising a nanogalvanic alloy. 4 . The apparatus of claim 3 wherein the nanogalvanic alloy of the desiccant comprises a powder containing substantially aluminum and at least one of tin, bismuth, indium, gallium, lead or carbon, and mixtures and alloys thereof. 5 . The apparatus of claim 1 wherein the nanogalvanic alloy within the reaction chamber comprises a powder containing substantially aluminum and at least one of tin, bismuth, indium, gallium, lead or carbon, and mixtures and alloys thereof. 6 . The apparatus of claim 1 wherein hydrogen is produced at about 7 PSI. 7 . The apparatus of claim 1 wherein the water vapor source uses mechanical, thermal, acoustic, ultrasonic, photonics, electromagnetic radiation, radiation and magnetic energy to form suspended water vapor. 8 . The apparatus of claim 1 wherein the water vapor source comprises an ultrasonic transducer. 9 . The apparatus of claim 1 wherein a controller controls the water vapor source to maintain a specified water vapor pressure within the reaction chamber. 10 . The apparatus of claim 1 wherein the water vapor source comprises atmospheric water vapor. 11 . The apparatus of claim 1 wherein the nanogalvanic alloy comprises at least one bar formed of nanogalvanic alloy powder. 12 . A method of generating hydrogen gas comprising: supplying water vapor; reacting water vapor with a nanogalvanic alloy to generate hydrogen gas. 13 . The method of claim 12 further comprising removing water vapor from the hydrogen gas. 14 . The method of claim 13 wherein removing water vapor is performed by a desiccant comprising a nanogalvanic alloy. 15 . The method of claim 14 wherein the nanogalvanic alloy of the desiccant comprises a powder containing substantially aluminum and at least one of tin, bismuth, indium, gallium, lead or carbon, and mixtures and alloys thereof. 16 . The method of claim 12 wherein the nanogalvanic alloy comprises a powder containing substantially aluminum and at least one of tin, bismuth, indium, gallium, lead or carbon, and mixtures and alloys thereof. 17 . The method of claim 12 wherein hydrogen gas is produced at about 7 PSI. 18 . The method of claim 12 wherein supplying water vapor uses mechanical, thermal, acoustic, ultrasonic, photonics, electromagnetic radiation, radiation and magnetic energy to form suspended water vapor. 19 . The method of claim 12 wherein supplying water vapor comprises supplying atmospheric water vapor. 20 . The method of claim 1 wherein the nanogalvanic alloy comprises at least one bar formed of nanogalvanic alloy powder.
