HYDROGEN STORAGE MATERIALS HAVING A HIGH DENSITY OF NON-CONVENTIONAL USEABLE HYDROGEN STORING SITES.

摘要

Disordered Multicomponent hydrogen storage material characterized by extraordinarily high storage capacity due to a high density of useable hydrogen storage sites (greater than 1023 defect sites/cc) and/or an extremely small crystallite size, as shown on the graph in the figure. The hydrogen storage material can be employed for electrochemical, fuel cell and gas phase applications. The material may be selected from either of the modified LaNi5 or modified TiNi families formulated to have a crystallite size of less than 200 Angstroms and most preferably less than 100 Angstroms.
