<P>PROBLEM TO BE SOLVED: To provide a hydrogen storage material excellent in heat transfer properties and a method for producing the hydrogen storage material. <P>SOLUTION: The hydrogen storage material comprises a hydrogen storage alloy and a carbon nanotube, wherein the carbon nanotube is bonded to the surface of the hydrogen storage alloy. Since the thermal contact resistance between the hydrogen storage alloy and the carbon nanotube (CNT) is small, one end of the CNT in the longitudinal direction is bonded to the hydrogen storage alloy and the CNT has excellent heat transfer properties in the length direction thereof, the hydrogen storage material has excellent heat transfer properties. The hydrogen storage material is obtained by placing the hydrogen storage alloy in an atmosphere to be heated, supplying a carbon source gas and growing the CNT from the surface of the hydrogen storage alloy by a chemical vapor deposition method. <P>COPYRIGHT: (C)2012,JPO&INPIT |
