Abstract: A corrosive resistant metal material covered with a conductive substance suitable for use in a component material requiring conductivity and corrosion resistance like electrical conductive material, electrical contact, electromagnetic wave shield, electrochemical electrode or antistatic material, specifically for component material requiring conductivity in sever condition of corrosive environment is provided. A corrosive resistant metal material covered with a conductive substance is formed by cladding a corrosive resistant metal selected from the group consisting of titanium, zirconium, tantalum, niobium and alloy thereof on a conductive metal selected from the group consisting of iron, aluminum, copper, titanium, magnesium, zirconium, tantalum, niobium, tungsten, nickel, chrome and alloy thereof, and covering a conductive surface finishing layer over surface of a corrosive resistant metal layer with a mixture of conductive substance and resinous binder.

Abstract: Disclosed is a hydrogen storage material and a production method thereof. The hydrogen storage material has a carbon material having: an interlayer space for hydrogen occlusion, produced by removal at least a portion of an organic compound from a graphite intercalation compound comprising graphite and the organic compound intercalated in the graphite; and an active point at which hydrogen is adsorbed, being produced on the remaining organic compound and/or a part of the hexagonal carbon layers defining the interlayer space. It has a layered lattice structure with hexagonal carbon layers and an expanded interlayer space, and its density determined in accordance with He equilibrium pressure density measuring method changes according as pre-equilibrium He pressures and falls in a range of 0.2 to 1.2 g/cm3 at pre-equilibrium pressures of 0.2 MPa and 0.8 MPa.
