PROBLEM TO BE SOLVED : To provide a composite of hydrides and a hydrogen storing material which contain a small amount of rare elements and are light in weight and capable of storing/releasing a large amount of hydrogen at a relatively low temperature, and a manufacturing method thereof. SOLUTION : The composite of hydrides is obtained by compounding in a mechanically mixing process one or more kinds of borohydrides represented by X(BH4)m(wherein m is a valence number of the element X) and one or more kinds of amides represented by Y(NH2)n(wherein n is a valence number of the element Y) and the manufacturing method thereof is provided. The hydrogen storing material is obtained by releasing all or a part of hydrogen contained in the composite of hydrides and the manufacturing method thereof is provided. COPYRIGHT : (C)2007, JPO&INPIT
