AlH is a metal hydride with a large gravimetric and volumetric hydrogen content (10.1 wt.% and 149kgH/m, respectively), and therefore it is promising as a hydrogen storage material. The high capacity and low desorption temperature (80150C) have attracted much attention. In situ X-ray diffraction measurements for the Al-H binary system at high pressures and temperatures were performed to investigate the hydrogenation of aluminum metal immersed in hydrogen fluid as well as the phase stability of the aluminum hydride formed.
