The Al-Li-Ni3Sn2 composites were prepared via milling method and their hydrolysis performance was presented in the paper. The milled Al-Li-Ni3Sn2 composites showed high hydrolysis performance at 30-600C, especially that Al-3.5wt%Li-20wt%Ni3Sncomposite had 100% and 1103 ml hydrogen/g of hydrogen yield within 20 min at 500C.The hydrolysis performance improvement of Al-Li-Ni3Sncomposite was due to the addition of Ni3Sn2 while Ni3Sn2 combined with Al and formed nano structure of Ni-based alloys deposited on the surface of Al. The structure of Al-(Ni alloy) could act as active sites in the hydrolysis process because the milled products such as AlNi, Al-NiSn and Al- Ni3Snhad high electrochemical activity in the hydrolysis process. Therefore, Al-Li-Ni3Sn2composites were a potential hydrogen source for fuel cell.
