全なものであった。However, the hydrogen electrode hardened with such a binder has insufficient strength and is damaged during handling during the manufacture of the battery, or inside the battery after completion. It is easily damaged, and its fragments may cause an internal short circuit or render it unusable. For this reason, at present, the hydrogen electrode is completely covered with a separator made of a non-woven fabric such as polypropylene (PP) to protect the hydrogen electrode itself.
We have taken measures to prevent inconvenience, but it is still incomplete.

行った。In the present invention, this hydrogen storage metal or its alloy powder is kneaded with a resin to obtain a desired hydrogen storage resin body. By integrating with the hydrogen storage metal or its alloy powder by this resin, without losing the hydrogen storage function,
Great strength can be obtained. And as for the mixing ratio,
As is clear from Table 1 below (Examples 1 and 2, Comparative Examples 1 to 5), hydrogen storage metal or its alloy powder may be blended in the range of 200 to 900 parts by weight with respect to 100 parts by weight of the resin. . The reason is that when the hydrogen storage metal or its alloy powder is less than 200 parts by weight, a sufficient hydrogen storage function cannot be obtained, and conversely, when it exceeds 900 parts by weight, the strength is reduced. is there. The resin used in Table 1 was low density polyethylene (LDPE), but similar results were obtained with other resins. Also,
Here, the hydrogen storage test was carried out by leaving it in a hydrogen gas at 1 atm and room temperature for 24 hours, then raising the temperature to 60 ° C., and quantifying the hydrogen released thereafter. Furthermore, the strength test of the obtained hydrogen storage resin body was performed by the bending test of JIS K7203.

使用することができる。As described above, according to the hydrogen storage resin body of the present invention, by mixing 200 to 900 parts by weight of the hydrogen storage metal or its alloy powder with 100 parts by weight of the resin,
It is possible to obtain a resin body having a sufficient hydrogen storage function and high strength. Therefore, when this is used as a hydrogen electrode (negative electrode) of a hydrogen battery or the like, unlike the conventional case, it is not damaged during handling during manufacturing of the battery, and thus good workability can be obtained. In addition, even after completion, damage in the battery can be effectively prevented,
The fragments and the like solve the problem of causing an internal short circuit. Therefore, it is not necessary to protect the hydrogen electrode with a separator such as a non-woven fabric, and the number of steps can be reduced. In addition to the above hydrogen electrode, the hydrogen storage resin body according to the present invention can be used as an excellent material for an internal combustion engine that uses hydrogen as a fuel and other energy storage systems.
