Outline of Final Research Achievements

New material search and hydride ion conduction mechanism analysis were carried out to develop the hydride conduction mechanism and the novel energy devices. The hydride ion conduction in the K2NiF4 type structure, which is the basic structure of the hydride ion conducting oxy-hydrides, proceeds mainly in the perovskite layer and hydride ion conduction in the perovskite layer is relatively faster than that of hydride ion in the rock salt layer. The K2NiF4 type La-Sr-Li-H-O based material was synthesized by sintering in a container sealed in a hydrogen atmosphere. Since larger quantities of samples can be obtained at one, the process was found to be suitable for the device verification has been established.
