Creation of intermediate temperature fast hydride ion conductor utilizing interstitialcy mechanism and investigation of the diffusion mechanism

Researcher
Outline

Recently, control of chemical reaction by applying electric fields has attracted attention. This research focuses on interstitialcy ion diffusion mechanism, which is one of the many-body motions of ions, and aims to create a intermediate-temperature fast hydride ion conductor that contributes to electrolytic hydrogenation reduction reactions.
