TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The acid adsorbent is polyacrylic acid polymers, silicates, carbons or metal hydroxide salts. The chemical hydride is a boron hydride. The aqueous reagent comprises water or an acidic solution. The acidic solution is solutions of hydrochloric acid, sulfuric acid, phosphoric acid, formic acid, acetic acid, citric acid, malic acid or maleic acid.    TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The reaction chamber and the liquid reagent storage chamber are arranged in a volume exchanging configuration. The liquid reagent storage chamber comprises an inner container. The reaction chamber comprises an inner container. (I) further comprises: a movable wall (130) or a flexible wall separating the fuel chamber and the liquid reagent storage chamber; an acid adsorbent separating the fuel chamber and the liquid reagent storage chamber; at least one gas permeable membrane in contact with the reaction chamber, where the membrane is configured to allow hydrogen to pass through the membrane while preventing solid and liquid materials from passing through the membrane; and a battery to power a liquid reagent regulator. The actuator configured to move the reaction chamber comprises a spring. The spring is configured to pull or push the reaction chamber. The hydrogen fuel cartridge further comprises: a liquid reagent regulator; a mixing element in fluid communication with the liquid reagent conduit line. The liquid reagent regulator is a peristaltic pump, a piezoelectric pump, a piston pump, a diaphragm pump, a centrifugal pump, an axial flow pump, a solenoid valve, a ball valve, a pinch valve, or a diaphragm valve. Preferred Method: The method further comprises: transporting the hydrogen to a hydrogen device comprising a fuel cell that generates electricity by oxidizing hydrogen, a hydrogen burning engine, or a hydrogen storage device; and transporting water from the fuel cell to the reaction chamber; and transporting water from the fuel cell to a chamber for storing the aqueous reagent or to a mixing element.
