Outline of Final Research Achievements

A feasibility of an energy conversion device using hydride conductors was investigated. K2NiF4 type structured hydride ion conductors showed pure ionic conductive behavior, indicating that the hydride conductor could be used as a solid-electrolyte for the devices. Symmetric cell using Pd electrodes and the solid-electrolyte successfully demonstrated a reaction from H2 to H- ion. This result revealed the possibility of developing an energy conversion hydride device. Further development of the solid hydride conductive materials and appropriate electrode materials could contribute to the establishment of a novel device with hydride redox reactions.
