（イ）産業上の利用分野
本発明は金属水素化物を利用して水素貯蔵あるいは蓄熱
等を行なうための金属水素化物容器に関する。DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a metal hydride container for storing hydrogen or storing heat using metal hydride.
（ロ）従来の技術
一般に金属水素化物容器においては、金属水素化物の脱
水素化および水素化反応を行なうための反応容器と、そ
の結果発生および吸収する熱の回収および供給を行なう
ための熱交換容器とが必要となる。なお、金属水素化物
は脱水素体して金属になるが、この場合も含めて本明細
書中では金属水素化物と称する。(b) Conventional technology In general, metal hydride containers include a reaction container for dehydrogenation and hydrogenation reactions of metal hydrides, and a heat exchanger for recovering and supplying the heat generated and absorbed as a result. A container is required. Note that a metal hydride becomes a metal when dehydrogenated, and this case is also referred to as a metal hydride in this specification.
従来、そのための容器構造として、上記反応容器と熱交
換容器とを別体に設け、その間をヒートパイプで連結す
る別体構造のものと１反応容器と熱交換容器とを一体化
してヒートパイプを不要とした一体構造のものとがある
が、顕熱損失を少なくする点や、コンパクト化の点では
一体構造の方が有利である。Conventionally, as a container structure for this purpose, the reaction container and the heat exchange container are provided separately and a heat pipe is used to connect them, and the other is a separate structure in which the reaction container and the heat exchange container are integrated to form a heat pipe. Although there is a one-piece structure that eliminates the need, the one-piece structure is more advantageous in terms of reducing sensible heat loss and making it more compact.
一方、金属水素化物は脱水素化および水素化反応を繰り
返すうちに、粉体は次第に崩壊して微細化し、反応に寄
与しなくなる。従って、このような時期を見計らって金
属水素化物を新しい粉体と交換する必要が生じる。On the other hand, as the metal hydride undergoes repeated dehydrogenation and hydrogenation reactions, the powder gradually disintegrates into fine particles and no longer contributes to the reaction. Therefore, it is necessary to replace the metal hydride with new powder at such times.
しかし、従来のこの種の容器構造は、例えば特開昭５４

た。However, the conventional container structure of this type is, for example,
As disclosed in JP-A-145831 and JP-A-58-47989, the structure did not take into account the exchange of metal hydrides in one reaction vessel, so it was necessary to use welding to exchange metal hydrides. This was an extremely difficult task as it required re-melting and cutting the piping.
（ハ）解決しようとする問題点
本発明は容器部分を一切破壊することなく、内部の金属
水素化物を簡単に取出し、交換することのできる金属水
素化物容器を提供することを目的とする。(c) Problems to be Solved It is an object of the present invention to provide a metal hydride container from which the metal hydride inside can be easily taken out and replaced without destroying any part of the container.
（ニ）問題点を解決するための手段 このため本発明は１円筒状耐圧容器の両端部に。(d) Means to solve the problem Therefore, the present invention applies to both ends of a cylindrical pressure-resistant container.
