(Industrial Application Field) The present invention relates to a hydrogen gas generating material. (Prior art) Conventionally, methods for producing hydrogen gas include a method of reacting a metal with an acid or alkali and a method of electrolyzing water, but the former method is difficult to use industrially. For this reason, electrolysis is generally adopted industrially. Furthermore, recently, a method of thermochemically decomposing water has also been proposed. (Problems to be Solved by the Invention) However, the electrolysis method and the thermochemical decomposition method of water have a problem in that they require a large amount of electric power and thermal energy. Therefore, an object of the present invention is to obtain a hydrogen gas generating material that is inexpensive, does not require energy such as electricity or heat, has high hydrogen gas generation efficiency, and is free from environmental pollution. (Means for Solving the Problems) As a means for solving the problems, the present invention has a layered structure in which fine metal particles are stacked, and the fine metal particles contain 5 to 50% tin, the balance aluminum and unavoidable metal particles. The present invention provides a hydrogen gas generating material characterized in that it is made of an aluminum alloy containing certain impurities. In an embodiment of the present invention, the hydrogen gas generating material is formed of a laminate having a layered structure in which fine metal particles are piled up as flat particles. Hydrogen gas generating material The present invention also comprises a metal sprayed coating formed on a substrate, the metal sprayed coating containing 5 to 50% tin,
The present invention provides a hydrogen gas generating material characterized in that it is formed using an aluminum alloy wire rod consisting of aluminum and unavoidable impurities. In this case, the base material includes mild steel, aluminum, copper and other metal materials, acrylic resin and other plastics, glass, ceramics, etc.
You can use anything you like. In addition, the shape of the base is
Any shape such as plate, sheet, band, etc. can be adopted. (Function) When the hydrogen gas generating material according to the present invention is simply immersed in water, the aluminum alloy reacts with water to generate high purity hydrogen gas. In particular, when aluminum is used as the base, the rate of hydrogen gas production increases significantly. Generally, it is well known that aluminum does not react even when immersed in water or hot water because the surface of aluminum is oxidized and becomes passive even in the atmosphere. Surprisingly, however, an aluminum alloy made by adding a predetermined amount of tin to aluminum reacts with water and generates hydrogen gas even when immersed in water at room temperature. Moreover, the rate of hydrogen gas generation increases as the temperature rises, and when this aluminum alloy is used to form a laminated body with a laminated structure consisting of a thermal spray coating or other fine metal particles on a substrate, the hydrogen gas generation rate of the alloy itself increases. It has become clear that this amount is approximately 70 to 80 times higher than that of the previous year. The present invention was completed based on this knowledge. The reason why the aluminum alloy and its thermal spray coating according to the present invention react with water to generate hydrogen gas and the reaction mechanism are not yet clear, but tin is uniformly dissolved in aluminum to a level exceeding its solid solubility limit. It is assumed that this is due to this. Furthermore, when a thermally sprayed coating is formed, the hydrogen gas production rate increases significantly, presumably because the thermally sprayed particles become flat and stacked to form a layered structure and are activated. The reason for limiting the biocomposition of the aluminum alloy is as follows. The reason why the tin content is set to 5 to 50% is that if the tin content is less than 5% or exceeds 50%, hydrogen generation is hardly observed and the object of the present invention cannot be achieved. Note that it is preferable to use aluminum and tin with as high a purity as possible. In the hydrogen gas generating material according to the present invention, for example, molten aluminum alloy is supplied from one end to a mold whose inner wall surface is maintained at a temperature higher than the freezing point of the molten metal, and is drawn out horizontally while solidifying from the other end. It can be produced by continuous casting, drawing the resulting aluminum alloy, and using this wire to form a thermal spray coating on a substrate by flame spraying or the like. Note that the melting points and densities of aluminum and tin are significantly different, and the solid solubility of tin in aluminum is extremely low. Since it is difficult to obtain a homogeneous coating because it is easy to form, a thermal spray coating may be formed directly using the molten metal itself. (Example) Using the continuous casting apparatus shown in FIG. 1, an aluminum alloy was cast in the following manner. In the figure, 1 is an electric furnace, 2 is a graphite crucible, 3 is a heating mold, 4 is a heater, 5 is a cooling device, 6 is a pinch roller, 7 is a molten metal, 8 is an ingot, and 9 is a cooling water supply port. First, aluminum (Al) with a purity of 99.99% and tin (Sn) with a purity of 99.9% are used as raw materials, and these are mixed into the composition shown in Table 1, melted in an electric furnace 1, and molded using a heater 4. 3 was heated and maintained at a temperature above the freezing point of the casting material, and a dummy bar (not shown) was set in the mold. Next, push the rod (not shown) into the graphite crucible 2 of the electric furnace 1.
is inserted to fill the mold 3 with molten metal, and then the pinch roller 6 is inserted while supplying cooling water to the cooling device 5.
Casting was started by rotating and pulling out the dummy bar, and aluminum alloy ingots each having a diameter of 8 mm were obtained. When the dummy bar is pulled out, the molten metal forms a solidified shell near the mold outlet, but since the mold is heated above the melting point of the aluminum alloy, the solidified interface protrudes into the mold as shown in the figure. . The solidified ingot 8 is further cooled by the cooling device 5. Next, each aluminum alloy ingot having the composition shown in Table 1 was drawn to obtain a wire rod having a diameter of 3.2 mm.

By the way, the old electrolytic cell (applied voltage 2V, current density 0.1A/mm 2 ) has 22ml/hr・cm 2 at room temperature, and about ml/hr・cm 2 at 75℃.
cm2 . Figure 2 shows the relationship between the hydrogen gas generation rate and water temperature when each hydrogen gas generation material consisting of a sprayed coating formed on an aluminum plate as a base is immersed in water.
Further, FIG. 3 shows the relationship between the hydrogen gas generation rate and the water temperature when each hydrogen gas generation material consisting of a thermally sprayed coating formed on an acrylic plate substrate is immersed in water. As is clear from the figure, the rate of hydrogen gas production is highly dependent on temperature and tin content. Furthermore, as is clear from the comparison of FIGS. 2 and 3, the hydrogen gas generation rate also changes depending on the material of the substrate, and the hydrogen gas generation rate is particularly fast when an aluminum plate is used as the substrate. (Effects of the Invention) As is clear from the above explanation, according to the present invention, it is possible to obtain a hydrogen gas generating material using inexpensive and harmless materials, and moreover, it is possible to obtain a hydrogen gas generating material using electricity and other energy for hydrogen gas generation. At 75℃, hydrogen gas production speed is approximately 300 times faster than that of old electrolyzers, and excellent results can be obtained.
