摘要： 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.

摘要： Methods and devices and aspects thereof for generating power using PEM fuel cell power systems comprising a rotary bed (or rotatable) reactor for hydrogen generation are disclosed. Hydrogen is generated by the hydrolysis of fuels such as lithium aluminum hydride and mixtures thereof. Water required for hydrolysis may be captured from the fuel cell exhaust. Water is preferably fed to the reactor in the form of a mist generated by an atomizer. An exemplary 750 We-h, 400 We PEM fuel cell power system may be characterized by a specific energy of about 550 We-h/kg and a specific power of about 290 We/kg. Turbidity fixtures within the reactor increase turbidity of fuel pellets within the reactor and improve the energy density of the system.

摘要： A chemical-looping system utilizes oxygen-carrier particles to produce syngas from carbonaceous fuels. The system provides a circuitous flow path for the oxygen-carrier particles, which are used to partially oxidize the fuel to produce syngas. The circuitous flow path can proceed through a plurality of unit operations, including a reducer, a conversion reactor, an oxidizer, and a combustor. The conversion reactor is designed to partially oxidize carbonaceous fuel in co-current flow with the oxygen-carrier particles to produce syngas. In embodiments including an oxidizer, the oxidizer is designed to at partially re-oxidize the carrier particles, yielding hydrogen that can be mixed with partially oxidized products from the conversion reactor to adjust syngas quality. The combustor can be used to fully oxidize the carrier particles traveling in a closed loop. Reactions carried out in the combustor are highly exothermic and yield thermal energy that is absorbed by the carrier particles. The absorbed energy is used at other parts of the process, including the conversion reactor, to drive endothermic reactions. In this manner the system can be operated autothermally or nearly so. Methods of producing syngas are also disclosed.

摘要： A process of generating a gas includes providing an encapsulation of reactive metal particles, releasing the reactive metal particles from the encapsulation, mixing the reactive metal particles in turbulent water, reacting the reactive metal particles in the turbulent water to generate hydrogen, cooling the turbulent water and the hydrogen with water jets, separating solids and liquids from the hydrogen, and providing the hydrogen to an electrochemical cell.
