## Description

- description: "Hydrogen incorporated into solids can adopt either protonic (H+)\r\nor
    hydridic (H−) characteristics depending on the position of the Fermi level of\r\nthe
    host material. In recent years, not only proton-conducting materials but also\r\nhydride-ion-conducting
    materials have been actively developed, enabling the\r\ndevelopment of novel electrochemical
    devices that exploit the amphoteric nature\r\nof hydrogen."
