| Title | Hydrogen gas generating member and hydrogen gas producing method therefor |
| Abstract |
(US9617622) A hydrogen gas generating member includes a metal alloy having dispersed aluminum. The metal alloy includes an Al―X alloy, where X is Sn: 10.1 to 99.5% by mass, Bi: 30.1 to 99.5% by mass, In: 10.1 to 99.5% by mass, Sn +Bi: 20.1 to 99.5% by mass, Sn +In: to 10 to 99.5% by mass, Bi+In: 20.1 to 99.5% by mass, or Sn+Bi+In: 20 to 99.5% by mass. Hydrogen gas is generated by bringing the hydrogen gas generating member into contact with water. |
| Scope of claims |
[claim1] 1. A hydrogen gas generating member comprising: an Al -- X alloy which comprises a matrix and Al dispersed in the matrix, wherein X is Sn: 60 to 99.5% by mass, Bi: 30.1 to 99.5% by mass, In: 10.1 to 99.5% by mass, Sn+Bi: 20.1 to 99.5% by mass, Sn+In: 80 to 99.5% by mass, Bi+In: 20.1 to 99.5% by mass, or Sn+Bi+In: 20 to 99.5% by mass, the Al -- X alloy is separated into a first solid phase of Al crystal grains and a second solid phase of crystal grains of the matrix, a number average domain diameter of the Al crystal grains is 0.01 to 500 mu m, and 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 Al -- X alloy is an Al -- X -- Y alloy that further comprises Y, and Y is Pb: 0.01 to 20% by mass, Zn: 0.01 to 30% by mass, Si: 0.01 to 20% by mass, Cd:0.01 to 20% by mass, Cu: 0.01 to 20% by mass, Fe: 0.01 to 5% by mass, Ga: 0.01 to 30% by mass, Ge: 0.01 to 30% by mass, Hg: 0.01 to 20% by mass, Mg: 0.01 to 20% by mass, Ni: 0.01 to 5% by mass, S: 0.01 to 5% by mass, or Mn: 0.01 to 5% by mass, the total content of Y is lower than 60% by weight even when a plurality of Y elements is contained in the alloy, and the content of X by weight is larger than half of the total content of Y by weight. [claim3] 3. The hydrogen gas generating member according to claim 1, wherein the hydrogen gas generating member comprises a plate having a rolling ratio of 30 to 99.99 %. [claim4] 4. The hydrogen gas generating member according to claim 1, wherein the hydrogen gas generating member comprises powders having a weight average particle diameter of 5 to 400 mu m. [claim5] 5. The hydrogen gas generating member according to claim 2, wherein the hydrogen gas generating member comprises a plate having a rolling ratio of 30 to 99.99 %. [claim6] 6. The hydrogen gas generating member according to claim 2, wherein the hydrogen gas generating member comprises powders having a weight average particle diameter of 5 400 mu m. |
