Abstract

A hydride ion conductor is represented by: MAMBH 4-x F x   Formula (1), where MA is selected from the group consisting of Ca, Sr, and Ba, MB is selected from the group consisting of Mg and Ca, and is different from MA, and x is 0<x<4.

Claims (13)

1 . A hydride ion conductor, wherein

the hydride ion conductor is represented by:

MAMBH 4-x F x   Formula (1), where

MA is selected from the group consisting of Ca, Sr, and Ba,

MB is selected from the group consisting of Mg and Ca, and is different from MA, and

x is 0<x<4.

2 . The hydride ion conductor according to claim 1 , wherein

the hydride ion conductor has a BaZnF 4 -type structure, and

conductivity at 300° C. of the hydride ion conductor is 10 −5 S/cm or higher.

3 . The hydride ion conductor according to claim 1 , wherein

MAMBH 4-x F x of Formula (1) is SrMgH 4-x F x or BaMgH 4-x F x , where x is 0<x<4.

4 . The hydride ion conductor according to claim 2 , wherein

MAMBH 4-x F x of Formula (1) is SrMgH 4-x F x or BaMgH 4-x F x , where x is 0<x<4.
