不発明は水素貯蔵合金により水素の取出し、又に吸蔵を
行わせる水素貯蔵槽の操業方法Ｖこ関するものである。DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The invention relates to a method of operating a hydrogen storage tank in which hydrogen is extracted or stored using a hydrogen storage alloy.
（従来の技術）
従来の水素貯蔵合金、例えばＦｅ−Ｔｉ 、 Ｌｃ−Ｎ
ｉ等等向内蔵た水素貯蔵槽は、その出口に圧力計及び流
量計が設置されて、該槽内の状態を計測しつＸ操業して

合金の特性との連連で本質的に困難である。(Prior Art) Conventional hydrogen storage alloys, such as Fe-Ti, Lc-N
A hydrogen storage tank with built-in isometrically oriented I, etc. is operated with a pressure gauge and a flow meter installed at its outlet to measure the condition inside the tank, but in general, the measurement of the condition inside the tank is , which is inherently difficult in conjunction with the properties of hydrogen storage alloys.
たとえば、水素貯蔵合金Ｍは、（１）式に示すような反
応式により、ある温度と圧力のもとで反応して、金属水
素化物ＭＨ２ｋ形成し、反応熱Ｑを放出する。For example, the hydrogen storage alloy M reacts under a certain temperature and pressure according to the reaction equation shown in equation (1), forms a metal hydride MH2k, and releases the heat of reaction Q.
Ｍ＋Ｈ２−一→ ＭＨ２＋Ｑ ・・・・・・・（１

力を下けたシすれば、（１）式に示す逆反応が光生じて
、吸熱し々から水素を放出する。M+H2-1 → MH2+Q ・・・・・・・・・(1
) There is a relationship as shown in FIG. 4 between the equilibrium dissociation pressure P of this reaction and the hydrogen content H/M in the metal hydride. When the temperature of this metal hydride is raised or the pressure is lowered, the reverse reaction shown in equation (1) occurs, and hydrogen is released while absorbing heat.
このように反応熱と水素の挙動には、極めて密接な関係
がある。In this way, there is an extremely close relationship between the heat of reaction and the behavior of hydrogen.
いま第４図において、Ａ−Ｂ間は水素の金属内への固溶

（α相と気体水素で２）、従って自由度は、＝２となり
、平衡解離圧力は、温度ｊ填成（水素含有量）によって
変化する。In FIG. 4, the area between A and B is a solid solution region of hydrogen in the metal, which is called the α phase, and since the crystal structure of the metal does not change, hydrogen is dissolved therein. Gibbs
As the phase law of (2) formula % formula % (2) f: degree of freedom of a certain system, C: number of independent components, P: number of phases 7 If applied, c-2 (metal and hydrogen c-2 ), P=2
(2 for α phase and gaseous hydrogen), therefore, the degree of freedom is =2, and the equilibrium dissociation pressure changes depending on the temperature j filling (hydrogen content).
次に、β〜Ｃ間では金属水素化物（β相）の形成が始ま

値と々す、水平部分（プラトーと称す）で表わされる。Next, metal hydride (β phase) begins to form between β and C and coexists with the solid solution (α phase), so P = 3 (α phase, β
phase and gaseous hydrogen 3) While flying, degrees of freedom f = 2-3 + 2
= 1, and the equilibrium dissociation pressure does not change depending on the hydrogen content when the temperature is constant, and is represented by a horizontal portion (referred to as a plateau) that remains at a constant value as shown in FIG.
なお、この曲線は温度によって変るが、この場合の曲線
は、読図の点線のようになる。Note that this curve changes depending on the temperature, but in this case the curve looks like the dotted line in the diagram.
一般に、この第４図において有効に水素の吸蔵・放出過
程を活用できるのは、プラトーと呼ばれる上記水平部分
である。従って有効に水素の吸蔵・放出反応を行なわせ

いことから、外部的には圧力を計測するのみでは槽内に
存在する水素の含有量を推定することは、本質的に困難

従来法という）、水素を吸収した粉体層中の残存水素量
を測定する方法が取られているが、この方法は実際に通
過した水素量は把握できても、今後の予測を行うことは
できない。Generally, in FIG. 4, the horizontal portion called the plateau is where the hydrogen storage and desorption process can be effectively utilized. Therefore, since the pressure in the area where hydrogen storage and release reactions occur effectively does not change depending on the amount of hydrogen contained, it is not possible to estimate the hydrogen content in the tank by simply measuring the pressure externally. It is essentially difficult to do so, and conventional methods include installing a strain measuring device inside the tank to measure the amount of expansion (Japanese Unexamined Patent Publication No. 58-95603, hereinafter referred to as the conventional method), and the method of absorbing hydrogen. A method has been used to measure the amount of hydrogen remaining in the powder layer, but although this method can determine the amount of hydrogen that has actually passed through, it cannot predict the future.
それは（１）式にて示される反応は、熱の吸収または放
出を伴う反応であるために、反応の発生により、水素化
物の温度が変化し、その温度変化が平衡解離圧を変え、
その結果として、また反応速度が変わるというように相
互に関連した複雑な反応系を形成するので、流量の積算
のみでは、この反応の推移を予測することはできないの
である。This is because the reaction represented by equation (1) is a reaction that involves the absorption or release of heat, so the temperature of the hydride changes due to the occurrence of the reaction, and this temperature change changes the equilibrium dissociation pressure.
As a result, a complex interrelated reaction system is formed in which the reaction rate changes, so the course of this reaction cannot be predicted only by integrating the flow rate.

度々あった。(Problems to be Solved by the Invention) In this way, in the conventional method, if hydrogen continues to be generated from a certain state, it is unclear how the temperature inside the tank will change and how hydrogen will be generated. There were many cases where the hydrogen ran out during the operation, or the temperature inside the tank rose too much, causing the hydrogen generation rate to become faster than necessary, resulting in the operation being interrupted.
