Abstract

A solid-state hydrogen storage device and a solid-state hydrogen storage system are provided. The solid-state hydrogen storage device includes a storage unit that stores a first hydrogen storage material therein and a heat medium pipe that is disposed in the storage unit including a heat medium and a second hydrogen storage material. The heat medium pipe includes a separating pipe disposed therein to separate the heat medium and the second hydrogen storage material from each other, and the second hydrogen storage material is disposed in the separating pipe.

First claim

What is claimed:

1 . A solid-state hydrogen storage device, comprising:
a storage unit configured to store a first hydrogen storage material therein; and a heat medium pipe disposed in the storage unit including a heat medium and a second hydrogen storage material, wherein the heat medium pipe includes a separating pipe disposed therein to separate the heat medium and the second hydrogen storage material from each other, and the second hydrogen storage material is disposed in the separating pipe.

2 . The solid-state hydrogen storage device of claim 1 , wherein the second hydrogen storage material releases heat during hydrogen absorption.

3 . The solid-state hydrogen storage device of claim 1 , wherein the separating pipe comprises steel, aluminum (Al), or copper (Cu).

4 . The solid-state hydrogen storage device of claim 1 , wherein the first hydrogen storage material is selected from the group consisting of a complex metal hydride, a metal hydride, a chemical hydride, a hydrogen storage alloy, and a combination thereof.

5 . The solid-state hydrogen storage device of claim 4 , wherein the complex metal hydride is selected from the group consisting of M 1 AlH 4 , M 2 (AlH 4 ) 2 , M 3 BH 4 , M 4 (BH 4 ) 2 , M 5 (BH 4 ) 3 , M 6 NH 2 , M 7 (NH 2 ) 2 , Li 2 NH, MgNH, lithium-magnesium amide, lithium-magnesium imide, and a combination thereof,
wherein M 1 is Li, Na, or Al, M 2 is Mg or Ca, M 3 is Li, Na, or K, M 4 is Mg or Ca, M 5 is Al or Ti, M 6 is Li or Na, and M 7 is Mg or Ca.

6 . The solid-state hydrogen storage device of claim 4 , wherein the metal hydride is M 8 H, M 9 H 2 , or a combination thereof, wherein M 8 is Li, Na, K, Rb, or Cs, and M 9 is Mg, Ca, Sc, Ti, or V.

7 . The solid-state hydrogen storage device of claim 4 , wherein the chemical hydride is selected from the group consisting of AlH 3 , NH 3 BH 3 , NH 4 B 3 H 8 , NH 2 B 2 H 5 , NaBP 2 H 8 , and a combination thereof.

8 . The solid-state hydrogen storage device of claim 4 , wherein the first hydrogen storage material is NaAlH 4 , or a composite including Mg(NH 2 ) 2 and LiH.

9 . The solid-state hydrogen storage device of claim 1 , wherein the hydrogen storage alloy is a Ti—Cr—V alloy, TiFe, Pd-M 10 , Li-M 11 , a Mg—Co alloy, a La—Ni alloy, or a combination thereof, wherein M 10 indicates Ba, Y, or La, and M 11 indicates Ti, V, Zr, Nb, or Hf.

10 . The solid-state hydrogen storage device of claim 9 , wherein the second hydrogen storage material is an Fe—Ti alloy or a La—Ni alloy.

11 . The solid-state hydrogen storage device of claim 1 , wherein the heat medium is water, air, oil, or a combination thereof.

12 . The solid-state hydrogen storage device of claim 1 , wherein the solid-state hydrogen storage device is for a vehicle.

13 . A solid-state hydrogen storage system, comprising:
a storage unit configured to store a first hydrogen storage material therein; and a heat medium pipe disposed in the storage unit including a heat medium and a second hydrogen storage material, wherein the heat medium pipe includes a separating pipe disposed therein to separate the heat medium and the second hydrogen storage material from each other, and the second hydrogen storage material is disposed in the separating pipe, wherein heat is released from the second hydrogen storage material during hydrogen absorption, and wherein the heat released during the hydrogen absorption is supplied to the first hydrogen storage material included in the storage unit through the heat medium included in the heat medium pipe, thereby releasing hydrogen from the first hydrogen storage material.

14 . The solid-state hydrogen storage system of claim 13 , wherein the separating pipe comprises steel, aluminum (Al), or copper (Cu).

15 . The solid-state hydrogen storage system of claim 13 , wherein the first hydrogen storage material is NaAlH 4 , or a composite including Mg(NH 2 ) 2 and LiH.

16 . The solid-state hydrogen storage system of claim 13 , wherein the second hydrogen storage material is an Fe—Ti alloy or a La—Ni alloy.

17 . The solid-state hydrogen storage system of claim 13 , wherein the solid-state hydrogen storage system is for a vehicle.

18 . A vehicle comprising a solid-state hydrogen storage device of claim 1 .
