Hydrogen storage material, production method of the hydrogen storage material, hydrogen supply system, fuel cell, internal combustion engine and vehicle

摘要

A hydrogen storage material includes: a first storage material body (1) which stores hydrogen; and a second storage material body (2) which stores hydrogen, and coats a surface of the first storage material body (1). A hydrogen equilibrium pressure (HP) of the second storage material body (2) is lower than that of the first storage material body (1) at the hydrogen generation temperature of the first storage material body (1).
