Activation of Mg2Ni alloy towards initial hydrogen uptake by treatment with water vapor and organic compounds
Keywords
Hydrogen as fuel
Abstract
The magnesium nickel alloy, Mg2Ni, is a good candidate for the storage of hydrogen. One problem associated with the use of this alloy for hydrogen storage is the difficulty of its activation for initial hydrogen uptake. A great deal of research has been done in this area. However, the resulting methods require hazardous conditions and reagents and/or prohibitively long periods of time. It has been found in this laboratory that water vapor can be used to activate Mg2Ni for hydrogen uptake in as little as one hour at ambient temperature and pressure. This finding is particularly interesting considering the long-held view of water acting as a poison in metallic hydrogen storage systems. It has been demonstrated in this laboratory that selective humidity levels can be used to activate or deactivate the alloy towards initial hydrogen uptake. The effects of long term exposure to 100% humidity on the activation of the Mg2Ni alloy and the effects of repeated cycling on the longevity of activation have also been studied. A brief study, of the application of organic solvents towards the activation of the alloy has also been included.
