Synthetic nanocomposite MgH₂/5 wt. % TiMn₂ powders for solid-hydrogen storage tank integrated with PEM fuel cell.

ABSTRACT: Storing hydrogen gas into cylinders under high pressure of 350 bar is not safe and still needs many intensive studies dedic ated for tank's manufacturing. Liquid hydrogen faces also severe practical difficulties due to its very low density, leading to larger fuel tanks three times larger than traditional gasoline tank. Moreover, converting hydrogen gas into liquid phase is not an economic process since it consumes high energy needed to cool down the gas temperature to -252.8 °C. One practical solution is storing hydrogen gas in metal lattice such as Mg powder and its nanocomposites in the form of MgH₂. There are two major issues should be solved first. One related to MgH₂ in which its inherent poor hydrogenation/dehydrogenation kinetics and high thermal stability must
