A hydrogen storage material is disclosed with no collapse due to pulverization of hydrogen storage alloy particles by repeated hydrogen absorption and desorption thereby permitting repeated use while manifesting excellent electric and thermal conductivities. Pressure molding of hydrogen storage alloy particles, each being covered with a plated metal film having microgranules of a thermoplastic resin, at a temperature higher than a glass transition temperature or a melting point of and below a thermal decomposition temperature of the thermoplastic resin can produce a porous hydrogen storage material of hydrogen storage alloy particles being bonded to each other via the thermoplastic resin. The hydrogen storage material can become firm and strong because the plated metal films covering the hydrogen storage alloy particles are clasped with each other complexly.
A hydrogen storage material comprising hydrogen storage alloy particles, each surface of said particles being covered with a plated metal film having microgranules of a thermoplastic resin, molded into a porous body having a three-dimensionally communicating space facing most of said hydrogen storage alloy particles directly or via said plated film, wherein said space is occupied in part by said thermoplastic resin so as to effect firm binding between said hydrogen storage alloy particles, and wherein said plated metal film on adjacent said particles is mechanically bonded together.
