Hydrogenation pressure-temperature conditions of A6061 alloys were investigated at ultra-high pressures. Hydrogénation of these alloys at 550°C and above 6 GPa formed AlH 3. This pressure was two orders of magnitude higher than the pressure where these alloys were used as hydrogen storage vessels for fuel cell vehicles. Thus, it was concluded that A6061 alloys were not hydrogenated at the pressure-temperature conditions where hydrogen storage vessels were used.
