Low pressure nickel hydrogen cell

Abstract: A new sealed rechargeable electric fuel cell of the type using a reoxidizable nickel hydroxide as the positive electrode reactant and hydrogen as the negative electrode reactant. The cell uses a hexagonal nickel - rare earth metal hydride compound for storage of hydrogen gas which causes the cell to be maintained at a low gas pressure during charging and discharging.

Hydrogen generation by means of the aluminum/water reaction

Abstract: An aluminum amalgam will react with water at ordinary temperatures with the formation of aluminum hydroxide and the liberation of free hydrogen. In the case of a block or sheet of the metal having an amalgamated surface, this reaction will continue until all the aluminum has been consumed. The reaction rate is observed to be temperature dependent, and this affords a simple means of regulating the output of hydrogen. If the supply of water and disposal of waste is discounted the reaction is shown to be superior, on a volumetric basis, to all other common means of producing hydrogen, and furthermore is competitive on a weight and cost basis with other chemical production methods. The inherent simplicity of such a scheme for hydrogen generation offers attractive advantages in terms of reliability.

Condensed Phase Metal-Hydrogen Systems and their Role in Controlled Fusion Reactors

Abstract: The properties of metallic and saline hydrides and their corresponding deuterides and tritides of possible interest to controlled fusion reactor technology are reviewed Topics discussed include the effect of hydrogen on the strength of structural materials, the solubilities of hydrogen and its isotopes in metals, the Li-H system, and the use of metal hydrides as hydrogen storage and shield materials
