を利用した水素貯蔵方法が注目されている。Hydrogen has a wider range of ignitable combustion limits than petroleum-based fuels, and has high thermal efficiency, so it is viewed as a promising fuel for future power sources. Conventional hydrogen storage methods have generally been to store it as liquefied hydrogen in a cryogenic storage tank or as a high-pressure gas in a high-pressure container. A hydrogen storage method that utilizes the property of occluding a large amount of hydrogen gas in the form of an interstitial bond under a certain equilibrium pressure and devolatilizing the occluded hydrogen gas at a different equilibrium pressure is attracting attention.

ていた。However, one of the drawbacks of the hydrogen gas storage method using metal hydrides is that it is difficult to indicate the amount of hydrogen stored in the metal hydrides. In other words, when hydrogen is stored using a single type of metal hydride, the relationship between the amount of hydrogen stored in the metal hydride (H/M) and the equilibrium pressure is linear (-
For example, the amount of gas stored in a high-pressure gas container cannot be easily indicated by pressure measurement, such as by indicating the amount of gas remaining in a high-pressure gas container with a pressure gauge. - Conventionally, the equilibrium pressure and temperature were measured and a pressure-composition-isotherm diagram (P-
Therefore, it was necessary to calculate the storage amount from the CT diagram (CT diagram).

で簡明に行なうことか可能となる。In order to achieve the above object, the present invention provides a metal hydride in which hydrogen is to be stored so that the relationship between the hydrogen storage amount (H/M) and the equilibrium pressure is linear with respect to the amount of the metal hydride. It is characterized by the use of a mixture of several types of metal hydrides. By doing this,
When a metal hydride is used to store hydrogen as a power fuel, it becomes possible to easily indicate the amount of remaining fuel (indication of hydrogen storage amount) by ordinary pressure measurement.
