Title: Two step novel hydrogen system using additives to enhance hydrogen release from the hydrolysis of alane and activated aluminum

Patent ·
OSTI ID:1227622
; ;

A system for the generation of hydrogen for use in portable power systems is set forth utilizing a two-step process that involves the thermal decomposition of AlH.sub.3 (10 wt % H.sub.2) followed by the hydrolysis of the activated aluminum (Al*) byproduct to release additional H.sub.2. Additionally, a process in which water is added directly without prior history to the AlH.sub.3:PA composite is also disclosed.
