Abstract:
A variety of proton (H + )–conducting oxides are known, including those used in electrochemical devices such as fuel cells. In contrast, pure H – conduction, not mixed with electron conduction, has not been demonstrated for oxide-based materials. Considering that hydride ions have an ionic size appropriate for fast transport and also a strong reducing ability suitable for high-energy storage and conversion devices, we prepared a series of K 2 NiF 4 -type oxyhydrides, La 2- x-y Sr x + y LiH 1- x + y O 3- y , in the hope of observing such H – conductors. The performance of an all-solid-state TiH 2 / o -La 2 LiHO 3 ( x = y = 0, o : orthorhombic)/Ti cell provided conclusive evidence of pure H – conduction.
