Al-Mg Alloy Powders for Hydrogen Storage

Abstract:

To develop hydrogen storage materials is the key to hydrogen storage. Magnesium theoretically stores 7.6 wt.% hydrogen, although it requires heating to above 300°C in order to release hydrogen. This limits its use for mobile application. However, due to its low price and abundance magnesium should still be considered as a potential candidate for hydrogen storage e.g. in stationary applications. Recent advances in Al-Mg alloy powders for hydrogen storage is presented in this paper. The main focus is on preparation of Mg-Al alloy and hydrogen storage properties of Mg-Al alloys. It is pointed the microstructure and components of Nano Mg-Al alloy have a great impact on the hydrogen-storage properties. Electrochemical deposition will be used to prepare the Nano Mg-Al alloy. Research will focuse on the nucleation mechanism and the influence of microstructure and components of the alloy on the hydrogen-storage properties.
