NOVELTY - An integrated hydrogen- and carbon dioxide-free air delivery system (74) comprises a sealable containment tank (77) for reacting water and an alkaline metal; an alkaline metal injector (92); a sealable holding tank (152) for reacting an aqueous sodium hydroxide solution and ambient air; an air pump (207) for inputting and bubbling air through the NaOH solution; and a piping assembly (71).    USE - For generating H2 and removing CO2 from the air to supply oxygen to a fuel cell.    ADVANTAGE - The delivery system is compact such that it requires no more room than conventional gasoline fuel tanks in vehicles. It is less sensitive to road shakes or movement and to temperature differentials such as required for use in motor vehicles. The hydrogen is produced up to 99.99% pure and free of CO2 and other contaminants. The life of the fuel cell is extended because the air delivered is free of CO2, thus producing efficient power over a longer period of time. It allows more transference of electrical potential and greater electrical power output, and produces zero emissions. Its by-products can be recycled back to the original alkaline metal.    DETAILED DESCRIPTION - An integrated hydrogen and carbon dioxide (CO2) free air delivery system comprises a sealable containment tank; a variable alkaline metal injector; a sealable holding tank; an air pump; and a piping assembly. The containment tank includes a lower portion (80) for holding water, into which an alkaline metal is to be introduced; an upper portion (86) for holding hydrogen gas (H2) produced by the chemical reaction between the alkaline metal and the water; and sealable opening(s) for introducing water and outletting H2. The alkaline metal injector is sealably mounted to the upper portion of the containment tank, and is incrementally movable to introduce an incremental portion of the alkaline metal into the tank. The holding tank has a lower portion (155) for holding an aqueous sodium hydroxide (NaOH) solution into which ambient air is to be contacted; an upper portion (164) for holding CO2-free air produced by the chemical reaction between the NaOH solution and the air; sealable opening(s) for introducing the NaOH solution and outletting the CO2-free air (167, 170); and an air inlet (158). The air pump is connectable to the air inlet to input and bubble air through the NaOH solution to remove the CO2 from the air. The piping assembly has a valved H2 pipe (185) connectable to the containment tank and to a fuel inlet (195) of a fuel cell (20); a valved NaOH solution pipe (198) connectable to the containment and holding tanks for conducting NaOH solution from the containment tank to the holding tank; and a valved CO2-free pipe (182) connectable to the holding tank and to the fuel inlet of the fuel cell for conducting the CO2-free air from the holding tank to the fuel inlet of the fuel cell.
