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