AIH3 The potential for using aluminum hydride, AIH3, for vehicular hydrogen storage was explored by Sandrock [44]. It is shown that particle-size control and doping of AIH3 with small levels of alkali metal hydrides (e.g., LiH) results in accelerated desorption rates. 

The desorption kinetics is limited by nucleation and growth of the aluminum particles and not by diffusion through a surface oxide as was inihally expected. Doping of AIH3 with small levels of the alkali metal hydrides LiH, NaH, and KH results in accelerated H2 desorption rates at low temperature. Approximately 7-8 wt% hydrogen was released below 448 K from...
