| Title | Hydrogen gas generating member and hydrogen gas producing method therefor |
| Abstract |
(EP2213617) There is provided a hydrogen gas generating member which safely facilitates the hydrogen gas generation reaction by bringing an Al alloy which is subjected to rolling treatment or powdering treatment into contact with water. A hydrogen gas generating member 20 includes a texture in which Al is finely dispersed in a metal matrix, where hydrogen gas is generated by bringing the hydrogen gas generating member into contact with water. A fixing member 14 for mounting the hydrogen gas generating member 20 is provided in a hydrogen generating apparatus 10 and is brought into contact with a water 15 that is stored inside. The hydrogen gas generated from the surface is supplied outside through a hydrogen gas collecting pipe 12 and stored in a storage tank (not shown). |
| Scope of claims |
[claim1] 1. A hydrogen gas generating member comprising: a texture in which Al is finely dispersed in a metal matrix, wherein hydrogen gas is generated by bringing the hydrogen gas generating member into contact with water. [claim2] 2. The hydrogen gas generating member according to claim 1, wherein the hydrogen gas generating member is separated into Al having a mutually different composition in a liquid phase state and another liquid phase and the two-liquid phase separation is present. [claim3] 3. The hydrogen gas generating member according to claim 1 or 2, wherein the hydrogen gas generating member is an Al-X alloy and X is at least one selected from Sn, Bi, and In. [claim4] 4. The hydrogen gas generating member according to claim 3, wherein the hydrogen gas generating member is an Al-X alloy and X is selected from Sn: 10.1 to 99.5% (mass percent: hereinafter on the basis of mass percent), Bi: 30.1 to 99.5%, In: 10.1 to 99.5%, Sn+Bi: 20.1 to 99.5%, Sn+In: 10 to 99.5%, Bi+In: 20.1 to 99.5%, and Sn+Bi+In: 20 to 99.5%. [claim5] 5. The hydrogen gas generating member according to claim 3 or 4, wherein the Al-X alloy further includes Y and Y is at least one selected from Pb: 0.01 to 20%, Zn: 0.01 to 30%, Si: 0.01 to 20%, Cd: 0.01 to 20%, Cu: 0.01 to 20%, Fe: 0.01 to 5%, Ga: 0.01 to 30%, Ge: 0.01 to 30%, Hg: 0.01 to 20%, Mg: 0.01 to 20%, Ni: 0.01 to 5%, S: 0.01 to 5%, and Mn: 0.01 to 5%, the content is within the range of 60% even when a plurality of elements are contained, and the relation of X and Y is defined by 2X>Y. [claim6] 6. The hydrogen gas generating member according to any one of claims 1 to 5, wherein the hydrogen gas generating member is rolled and processed. [claim7] 7. The hydrogen gas generating member according to any one of claims 1 to 5, wherein the hydrogen gas generating member is powdered. [claim8] 8. A process for producing hydrogen gas comprising a step of: bringing the hydrogen gas generating member according to any one of claims 1 to 7 into contact with water to generate hydrogen gas. |
