Abstract: A system for controlling contamination in hydrogen production from water-reactive aluminum includes at least one reaction vessel. For example, each reaction vessel may include a container, a conduit, and a plurality of baffles. The container may define a volume, and the conduit may define an orifice outside of the container and spaced away from the container. The plurality of baffles may be disposed in the volume to form a tortuous flow path through the volume to the orifice of the conduit to facilitate rapid production of a large quantity of hydrogen from water-reactive aluminum while reducing the likelihood that ejecta, aerosols, or a combination thereof, may escape the reaction vessel to interfere with end-use of the hydrogen produced.

Abstract: A system for hydrogen formation includes a container and at least one object. The container defines a reservoir and is flexible along the reservoir. The container forms a gas-tight seal between the reservoir and an atmosphere outside of the container. The at least one object includes aluminum in an activated form. The at least one object is disposed in an inert environment in the reservoir, and the activated form of the aluminum reactable to produce hydrogen in the reservoir upon exposure to water.

Abstract: Aluminum can be used as a fuel source when reacted with water if its native surrounding oxide coating is penetrated with a gallium-based eutectic. When discrete aluminum objects are treated in a heated bath of eutectic, the eutectic penetrates the oxide coating. After the aluminum objects are treated, the aluminum objects can be reacted in a reactor to produce hydrogen which can, for example, react with oxygen in a fuel cell to produce electricity, for use in a variety of applications.

Abstract: Materials, kits, and methods are directed to controlling reactability of activated aluminum to produce hydrogen when exposed to water. For example, a moisture-stabilized material may be treatable with one or more additives to form a water-reactive source of hydrogen. The moisture-stabilized material may include a bulk volume including aluminum, at least one activation metal disposed along the aluminum within the bulk volume, the at least one activation metal more noble than the aluminum, and a salt along at least an outer surface of the bulk volume, the salt dissolvable in water to form an ion-containing solution at a rate faster than a reaction rate of water with the aluminum of the bulk volume.
