A stable aluminum slurry fuel and related systems and methods of use are provided herein. Certain embodiments of the disclosure are related to an aluminum slurry fuel comprising a plurality of aluminum particles dispersed in a carrier fluid. In some embodiments, the aluminum particles comprise an activating composition comprising gallium and/or indium. Additionally, methods of making and using the aluminum slurry fuel are presented herein. For instance, the resultant aluminum slurry fuel may react exothermically with water over a wide range of temperatures to produce hydrogen. The resulting slurry fuel may be used as an energy source for various applications and/or for generating hydrogen for other applications.

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.

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.

A process for the obtention of a hydrogen-rich gas stream from aluminium waste by obtaining a process water resulting from contacting aluminium salt slag with tap water, adding the process water of the previous step to an aluminium waste in a solution, and the hydrolysis of that solution to obtain the gas stream. The process is capable to obtain a yield of reaction close to 100% in higher reaction times.
