Magnesium Hydride

Magnesium hydride is tetragonal system colorless cubic crystal or offwhite powder. It is hdyrogen source for fuel battery below 10000W. Hydrogen amount releasing by water is higher than 14.8wt%, which is much higher than high pressure gas hydrogen storage tank(70MPa,~5.5wt%0 and heavy metal hydrogen storage material(<2wt%). Further Magnesium dihydride is safe and highly efficient, which can improve present hydrogen storage method. Hydrolyzing magnesium dihydride as supply hydrogen system in pem fuel cell, which improve energy density of the system significantly. Solid Mg-H fuel battery systems with high-energy density is developed too and its whole energy density is 3-5times higher than lithium battery.
