· JVASP-85680· Rb3MgH5

Rb3MgH5 is an ionic metal hydride ceramic compound combining rubidium, magnesium, and hydrogen in a solid-state structure. This is a research-phase material studied primarily for hydrogen storage and solid-state energy applications rather than established industrial use. The material belongs to the complex metal hydride family, which is being explored as a potential solution for safe hydrogen storage in fuel cell systems and energy-dense applications where conventional storage methods are impractical.
