Abstract: A hydrogen gas cooled hydrogen storage element which includes a hydrogen storage alloy material in which hydrogen flow channels are provided. The flow channels provide pathways through the hydrogen storage material to allow for high speed hydrogen gas flow. A portion of the high speed hydrogen flow is stored within the storage material which releases its heat of hydride formation. The remainder of the hydrogen flows through the hydrogen storage material at a sufficient mass flow rate to remove the heat of hydride formation.

Abstract: A scooter powered by a hydrogen powered internal combustion engine fueled by a throttled stream of air into which a controlled amount of hydrogen is injected. A hydrogen fuel control system is used to control the amount of hydrogen injected into the throttled air stream using multiple parameters. The amount of hydrogen present in the hydrogen storage unit is monitored using an on-board hydrogen fuel measurement system utilizing a microcontroller and multiple sensors.

Abstract: A method for combining a first metal with a second metal where the melting point of the second metal is higher than the melting point of the first metal. The first and second metals are melted in separate crucibles. The second molten metal is introduced onto or into the first molten metal. Also described is a two-zone furnace for carrying out the method.

Abstract: Mechanically alloyed hydrogen storage materials having a major atomic percentage of magnesium and a minor atomic percentage of at least two elements selected from the group consisting of nickel, molybdenum, iron and titanium. Preferably the mechanical alloy comprises a multi-phase material, including at least one amorphous phase. Also, the at least two elements are preferably either nickel (from about 5 to 15 at. %) and molybdenum (from about 0.5 to 5 at. %) or iron (from about 5 to 15 at. %) and titanium (from about 5 to 15 at. %). The hydrogen storage materials are created by mechanical alloying in a milling apparatus under an inert atmosphere, such as argon, or a mixed atmosphere, such as argon and hydrogen. The speed and length of the milling are varied.
