<P>PROBLEM TO BE SOLVED: To advantageously solve the problem of a conventional metal-carbon combined hydrogen occluding material that the manufacturing process is complicate and the hydrogen storage amount per unit volume is small. <P>SOLUTION: The hydrogen occluding material is a composite material consisting of magnesium fine particles having 5 nm to 0.5 μm average particle size and a carbon material having 5 nm to 20 μm average particle size, contains 50-80 mass% magnesium and is produced by using a gas phase reaction apparatus comprising an inner pipe 1 and an outer pipe 2, introducing magnesium, a magnesium-nickel alloy, hydrogen, or the like into the gas phase reaction apparatus through a part A, introducing a hydrocarbon, argon, or the like through a part B and reacting the introduced substances with one another in a part C. <P>COPYRIGHT: (C)2004,JPO |
