Description
【発明の詳細な説明】 （産業上の利用分野） 本発明は水素ガス生成材に関する。[Detailed description of the invention] (Industrial application field) The present invention relates to hydrogen gas generating materials.
（従来の技術）
従来、水素ガスを生成させる方法としては、金属を酸や
アルカリと反応させる方法及び水を電気分解する方法が
知られているが、前者は工業的に利用することが困難で
あることから、工業的には電気分解法が一般に採用され
ている。また、最近では、水を熱化学的に分解する方法
も提案されている。(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.
（発明が解決しようとする問題点）
しかしながら、電気分解法や水の熱化学的分解法では、
多大の電力や熱エネルギーを必要とする問題がある。(Problems to be solved by the invention) However, in electrolysis and thermochemical decomposition of water,
There is a problem in that it requires a large amount of electric power and thermal energy.
従って、本発明は安価で、電気や熱等のエネルギーを必
要とせず、水素ガス生成能率が高く、しかも環境汚染の
恐れのない水素ガス生成材を得ることを目的とするもの
である。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.
（問題点を解決するための手段）
本発明は、前記問題を解決する手段として、金属微粒が

The present invention provides a hydrogen gas generating material characterized in that it is made of an aluminum alloy consisting of 0% aluminum and the remainder aluminum and inevitable impurities.

状を採用できる。Hydrogen gas generating material The present invention also provides a hydrogen gas generating material comprising a thermally sprayed metal coating formed on a substrate, wherein the metal is an aluminum alloy consisting of 5 to 50% tin, the balance being aluminum and unavoidable impurities. It provides a gas generating material. In this case, arbitrary materials such as mild steel, aluminum, copper and other metal materials, acrylic resin and other plastics, glass, and ceramics can be used as the base material. Further, the shape of the base body can be a plate, a sheet, a band, or any other arbitrary shape.
（作用）
本発明に係る水素ガス生成材は、水に浸漬するだけでア
ルミニウム合金が水と反応して高純度の水素ガスを生成
する。特に、基体としてアルミニウムを採用した場合に
は、水素ガス生成速度が著しく増大する。(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.
一般に、アルミニウムは大気中で乙表面が酸化されて不
動態となるため、水や温水に浸漬しても反応しないこと
は周知である。しかし、驚くべきことに、アルミニウム
に錫を所定量添加したアルミニウム合金は、常温の水に
浸漬しただけでら水と反応して水素ガスを発生する。し
かも、水素ガスの生成速度は、温度の上昇と共に増大し
、このアルミニウム合金を用いて基体上に溶射皮膜その
他の金属微粒からなる層状組織を有する積層体を形成す
ると、合金そのものの水素ガス生成速度の約７０〜８０
倍に達することが明らかとなった。Generally, it is well known that the surface of aluminum is oxidized in the atmosphere and becomes passive, so it does not react even when immersed in water or hot water. However, surprisingly, 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. about 70-80
It has been revealed that the number has doubled.
本発明は、この知見に基づいて完成されたものである。The present invention was completed based on this knowledge.
本発明に係るアルミニウム合金及びその溶射皮膜が水と
反応し水素ガスを生成する理由及びその反応機構等は解
明されていないが、アルミニウム中に錫をその固溶限以
上に均一に固溶させたことに起因するものと推測される
。また、溶射皮膜にした場合、水素ガス生成速度が著し
く増大するのは、溶射粒子が偏平状となって積み重なっ
た層状組織となって活性化するためと推測される。Although 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 clear, tin is uniformly dissolved in aluminum in an amount 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 generation rate increases significantly, presumably because the thermally sprayed particles become flat and stacked to form a layered structure and are activated.
アルミニウム合金の成分組成を限定した理由は次の通り
である。錫の含有量を５〜５０％としたのは、錫の含有
量が５％未満あるいは５０％を越えると、水素の発生が
殆ど見られず、本発明の目的を達成できないからである
。なお、アルミニウム及び錫はできるだけ高純度のもの
を使用するのが好ましい。The reason for limiting the composition 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.
本発明に係る水素ガス生成材は、例えば、内壁面を溶湯
の凝固点以上の温度に維持させた鋳型にその一端側から
アルミニウム合金の溶湯を供給し、他端側から凝固させ
つつ水平方向に引き抜いて連続鋳造し、得られるアルミ
ニウム合金を線引加工し、この線材を用いて火炎溶射法
等により基体上に溶射皮膜を形成することによって製造
できる。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 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.
なお、アルミニウムと錫の融点及び密度が著しく相異し
、またアルミニウム中への錫の固溶度が非常に小さいた
め、鋳型を冷却しながらアルミニウム合金を鋳造する方
法では、偏析を起こしたり欠陥を生じ易いため均質なも
のを得難いので、溶湯そのもので直接溶射皮膜を形成す
るようにしてもよい。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. Therefore, the method of casting aluminum alloy while cooling the mold may cause segregation or defects. 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.

た。First, aluminum (AI) with a purity of 99.99%,
Using tin (Sn) with a purity of 99.9% as a raw material, these are blended into the composition shown in Table 1 and melted in the electric furnace 1, while the mold 3 is heated by the heater 4 to a temperature above the freezing point of the casting material. A dummy bar (not shown) was set in the mold. Next, a push rod (not shown) is inserted into the graphite crucible 2 of the electric furnace 1 to fill the mold 3 with molten metal, and the pinch roller 6 is rotated while supplying cooling water to the cooling device 5. Casting was started by driving and pulling out the dummy bar, and aluminum alloy ingots each having a diameter of 8+no+ 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 wire-drawn to obtain a wire rod having a diameter of 3.2 mm.
