1. A hydrogen purification and storage apparatus comprising:
a hydrogen supply unit;
a reaction unit connected to the hydrogen supply unit via a hydrogen supply line, the reaction unit comprising a hydrogen storage material and a catalyst configured to accelerate hydrogenation of the hydrogen storage material; and
a compressor installed in the hydrogen supply line, the compressor being configured to compress hydrogen supplied from the hydrogen supply unit, wherein
the hydrogen storage material comprises a liquid organic hydrogen carrier (LOHC);
wherein the hydrogen supply line comprises:
a first hydrogen supply line configured to interconnect the hydrogen supply unit and the compressor;
a second hydrogen supply line configured to interconnect the compressor and the reaction unit; and
a third hydrogen supply line configured to interconnect the compressor and the reaction unit along a path different from a path of the second hydrogen supply line, the third hydrogen supply line having a buffer tank.
 
15. A hydrogen purification and storage method using the hydrogen purification and storage apparatus according to claim 1, wherein the hydrogen purification and storage method comprises reacting hydrogen supplied from the hydrogen supply unit to the reaction unit and the hydrogen storage material in the reaction unit with each other.
