Abstract

PURPOSE:To provide an economical means of transporting hydrogen by using a lightweight, high strength material for the structural member of a cylinder, and forming a hydrogen loss prevention function with a hydrogen absorbing and storing metal. CONSTITUTION:A lightweight, high strength material 3 is molded by using HT/ EXPOXY, HM/EPOXY which are compound of carbon fiber and epoxy resin, or polyamide fiber. A hydrogen absorbing and storing metal layer 4 which is a thin layer of Mg alloy, Ti-Fe family alloy, La alloy such as LaNi5 and the like is adhered to the inner surface of said molded material 3. Since the hydrogen absorbing and storing metal layer 4 absorbes the hydrogen below a certain temperature and a certain range of pressure, and rejects further penetration of the hydrogen, it can act as a barrier against the hydrogen proliferation. In this manner, a lightweight hydrogen cylinder can be formed.

効率は非常に悪い。Conventionally, high-pressure cylinders and liquid hydrogen cylinders have been used as transportable hydrogen storage containers. However, high-pressure cylinders are made of thick-walled steel to withstand high pressures of around 150 atmospheres, and are extremely heavy, each filled with 7 m of hydrogen gas weighing 60 Ky, making transportation difficult. economic efficiency is very poor.

また、液体水素ボンベは容器の構造を真空断熱構造にし

かった。In addition, liquid hydrogen cylinders have a vacuum-insulated container structure, which makes them vulnerable to shocks, and the cost of the cylinders is high. Thus, no economical means of transporting hydrogen was provided.

ンベが可能となる。The key points of the present invention are to significantly reduce the weight of the cylinder body by using a lightweight, high-strength material as the structural material of the cylinder, and to provide a hydrogen dissipation prevention function that the lightweight, high-strength material does not have.
This is achieved by utilizing the characteristics of hydrogen-absorbing metals. Hydrogen storage metals store a certain amount of hydrogen at a certain temperature and under a certain range of pressure, but once a certain amount of hydrogen has been stored, they cannot be stored even if further pressure is applied, and hydrogen cannot pass through or penetrate.
Stop. Therefore, the hydrogen storage metal layer supported by the lightweight high-strength material does not absorb hydrogen even if more hydrogen is injected than the storage capacity of the hydrogen storage metal layer, and a barrier is formed here to prevent hydrogen diffusion. . Therefore, the thinner the hydrogen storage metal layer, the
The higher the pressure resistance of the lightweight, high-strength material, the lighter it is and the more hydrogen gas it can store. This makes it possible to create a hydrogen cylinder whose main body is nearly 115% lighter than conventional cylinders.

以下、本発明を図に従って詳しく説明する。Hereinafter, the present invention will be explained in detail with reference to the drawings.

Furthermore, on top of this, lightweight, high-strength materials for pressure resistance (
