Abstract
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).
