発明の名称（英語）	Hydrogen-containing electrically conductive inorganic compound
発明の概要（英語）	(EP1500631) Disclosed is a 12CaO . 7Al2O3 compound, a 12SrO . 7Al2O3 compound, or a mixed crystal compound of 12CaO . 7Al2O3 and 12SrO . 7Al2O3, which contains a negative hydrogen ion (H<->, H<2->, H2<->) at a concentration of 1 x 10<18> cm<-3> or more. A negative hydrogen ion comprising a primary component of a hydride ion is incorporated into C12A7 (12CaO . 7Al2O3), so that a function of being converted from an insulative material to an electrically conductive material in a sustained manner by means of irradiation with light can be exhibited even in the normal atmosphere at a room temperature. The present invention also provides a solid electrolyte capable of conducting a negative hydrogen ion, and means for releasing a hydride ion from the inside of a solid into a gaseous phase using an electric field. <IMAGE>
