| 總結: | Complex hydride systems for hydrogen (H<sub>2</sub>) generation for supplying fuel cells are being reviewed. In the first group, the hydride systems that are capable of generating H<sub>2</sub> through a mechanical dehydrogenation phenomenon at the ambient temperature are discussed. There are few quite diverse systems in this group such as lithium alanate (LiAlH<sub>4</sub>) with the following additives: nanoiron (n-Fe), lithium amide (LiNH<sub>2</sub>) (a hydride/hydride system) and manganese chloride MnCl<sub>2</sub> (a hydride/halide system). Another hydride/hydride system consists of lithium amide (LiNH<sub>2</sub>) and magnesium hydride (MgH<sub>2</sub>), and finally, there is a LiBH<sub>4</sub>-FeCl<sub>2</sub> (hydride/halide) system. These hydride systems are capable of releasing from ~4 to 7 wt.% H<sub>2 </sub>at the ambient temperature during a reasonably short duration of ball milling. The second group encompasses systems that generate H<sub>2</sub> at slightly elevated temperature (up to 100 °C). In this group lithium alanate (LiAlH<sub>4</sub>) ball milled with the nano-Fe and nano-TiN/TiC/ZrC additives is a prominent system that can relatively quickly generate up to 7 wt.% H<sub>2</sub> at 100 °C. The other hydride is manganese borohydride (Mn(BH<sub>4</sub>)<sub>2</sub>) obtained by mechano-chemical activation synthesis (MCAS). In a ball milled (2LiBH<sub>4</sub> + MnCl<sub>2</sub>) nanocomposite, Mn(BH<sub>4</sub>)<sub>2 </sub>co-existing with LiCl can desorb ~4.5 wt.% H<sub>2</sub> at 100 °C within a reasonable duration of dehydrogenation. Practical application aspects of hydride systems for H<sub>2 </sub>generation/storage are also briefly discussed.
