· JVASP-90812· PrAlH6

PrAlH6 is a praseodymium-aluminum hydride compound belonging to the rare-earth metal hydride family, formed through the incorporation of hydrogen into a praseodymium-aluminum intermetallic matrix. This material is primarily investigated in advanced hydrogen storage research and energy applications, where reversible hydride formation offers potential for solid-state hydrogen containment at moderate temperatures and pressures—an approach that could overcome safety and efficiency limitations of conventional gas or liquid hydrogen storage systems. PrAlH6 represents an experimental compound of significant interest to the hydrogen economy and materials-for-energy communities, though industrial deployment remains limited to research and development stages.
