Abstract
Official abstract text for this publication.
A hydrogen generation device capable of generating hydrogen using an inexpensive material is provided. The hydrogen generation device includes: a water flow path unit through which a solution flows in from outside and exits; a hydrogen generation unit made of a metal, the hydrogen generation unit generating hydrogen by a reaction with the flowing-in solution; and a hydrogen collection unit for collecting the generated hydrogen, wherein the hydrogen generation unit is disposed so that friction with the flowing-in solution peels off a surface film of the metal to expose an active surface of the metal, the metal being the hydrogen generation unit itself.
First claim
Opening claim text (preview).
1 . A hydrogen generation device, comprising: a water flow path unit through which a solution flows in from outside and exits; a hydrogen generation unit made of a metal, the hydrogen generation unit generating hydrogen by a reaction with the flowing-in solution; and a hydrogen collection unit for collecting the generated hydrogen, wherein the hydrogen generation unit is disposed so that friction with the flowing-in solution peels off a surface film of the metal to expose an active surface of the metal, the metal being the hydrogen generation unit itself. 2 . The hydrogen generation device according to claim 1 , wherein the hydrogen generation unit is disposed so that friction with the solution falling from a high place to a low place peels off a surface film of the metal to expose an active surface of the metal, the metal being the hydrogen generation unit itself. 3 . The hydrogen generation device according to claim 1 , wherein the solution is within an alkaline to neutral range or within the range of pH 7 to pH 14. 4 . The hydrogen generation device according to claim 3 , wherein the hydrogen generation unit is made of a metal that forms a surface film due to an electrochemical reaction in the solution. 5 . The hydrogen generation device according to claim 4 , wherein the hydrogen generation unit is made of any one of pure iron, carbon steel, and an alloy or a pure metal containing Ni, Zn, Al, Cu, Mg, Ti, Mn, and Ag. 6 . The hydrogen generation device according to claim 2 , wherein the solution is within an alkaline to neutral range or within the range of pH 7 to pH 14.
