K2FeH6
metal· JVASP-157726· K2FeH6
K2FeH6 (potassium iron hydride) is an intermetallic hydride compound combining potassium and iron with significant hydrogen content. This material remains largely experimental and is of primary interest in hydrogen storage research and advanced materials development, where its high hydrogen density and lightweight characteristics position it as a candidate for next-generation energy storage applications. Unlike conventional steel or cast irons, this compound belongs to a family of metal hydrides being investigated for solid-state hydrogen storage in fuel cell systems and energy conversion technologies.
