Many metals or alloys are known to react reversibly with hydrogen. That is, there is the following relationship: [MH]+Q[M]+H 2 ↑ (M is metal or alloy, Q is heat of reaction); heat is generated when hydrogen is absorbed, and heat is absorbed when hydrogen is released. And each metal or alloy has a unique hydrogen equilibrium pressure that is dependent on temperature.

金などが報告されている。 In this specification, metals or alloys that have been activated so that they can store a large amount of hydrogen, and metals or alloys that actually store hydrogen are collectively referred to as metal hydrides. The hydrogen storage and release reaction of metal hydrides is determined by the hydrogen storage capacity, reaction reversibility, and the amount of heat of reaction, including hydrogen storage equipment, heat exchange equipment, heat transfer equipment,

分に反応熱を取出せないことがある。 When a metal hydride is heated or depressurized to release hydrogen, or when heat is removed from a metal hydride or pressurized to absorb hydrogen, the problem is the maximum hydrogen storage capacity of the metal hydride. However, it is difficult to instantly determine how much hydrogen is stored. Therefore, the timing of switching from the hydrogen absorption reaction of the metal hydride to the hydrogen release reaction may be missed, and the heat of reaction may not be sufficiently extracted from the metal hydride.

た。 Conventional equipment for measuring the degree of hydrogenation of metal hydrides uses a gas flowmeter to measure the flow rate of hydrogen gas entering and exiting a reaction vessel filled with metal hydrides, and detects changes in the hydrogen gas pressure inside the reaction vessel. The amount of hydrogen stored in the metal hydride was calculated by measuring with a pressure gauge. However, gas flowmeters have the drawbacks of slow response, poor accuracy, complicated calculation process for the amount of absorbed hydrogen, and high price of gas flowmeters.

Reference numeral 11 denotes a cylindrical metal hydride filling device for filling metal hydride. The cylindrical metal hydride filling device 1 may have a cylindrical shape, a rectangular tube shape, a gently tapered truncated cone, or a truncated pyramid shape. The metal hydride filling device 1
Since the metal hydride reacts internally under hydrogen pressure, it must be able to withstand a pressure of at least 10 kg/cm 2 without causing hydrogen embrittlement.

ルミニウムなどの薄板で形成される。 The metal hydride filler 1 is connected to a metal hydride reaction vessel 2 via a filter 3 at one end. The filter 3 forms a hydrogen gas flow path through which hydrogen gas freely flows without passing through the metal hydride to be pulverized. Therefore, the filter 3 is made of a finely sintered body of stainless steel, nickel, etc., and is not susceptible to hydrogen embrittlement and does not transmit metal hydrides that are pulverized to a size of 5 μm or less. The other end of the metal hydride filler 1 is sealed, and a communication pipe 4 that forms a hydrogen gas flow path communicating with the metal hydride reaction vessel 2 is opened in the vicinity thereof. The communication pipe 4 is provided with a metal hydride filter similar to the filter 3 at the connecting portion of the metal hydride reaction vessel 2 and the like. At approximately the center of the metal hydride filling device 1, a partition wall 5 that does not allow metal hydride and hydrogen gas to pass therethrough is fixed at its edge. The partition wall 5 is made of a thin plate of stainless steel, copper, nickel, aluminum, or the like.

との反応量を測定することになる。 The volume of the filled metal hydride 6 expands and contracts as a result of the hydrogen absorption and release reaction, but the cylindrical wall and filter 3 of the metal hydride filling device 1 are hardly affected by the deformation and are exclusively formed into thin plates. A force that compressively deforms the partition wall 5 acts, and a change in the volume of the metal hydride 6 can be observed as a displacement in the uniaxial direction in the metal hydride filling device 1. (When the metal hydride absorbs hydrogen to its maximum capacity, the volume expands by about 20% compared to when the metal hydride releases hydrogen and is depleted of hydrogen.) Inside the metal hydride filling device 1 By providing the filter 3 and the communication pipe 4, the hydrogen gas pressure is the same as that inside the metal hydride reaction vessel 2, and the pressure difference between the compartments on both sides of the partition wall 5 is offset. Since the metal hydride filling device 1 is connected to the large-capacity metal hydride reaction container 2, as the temperature of the metal hydride reaction container 2 rises and falls, the metal hydride filling device 1 also becomes almost the same. The temperature remains the same. Since the compartment of the metal hydride filling device 1 is made to have the same hydrogen gas pressure and the same temperature as the metal hydride reaction container 2, the metal hydride 6 in the metal hydride filling device 1 and the metal hydride reaction container 2 Measuring the amount of reaction between the metal hydride 6 in the metal hydride filling device 1 and hydrogen by using the same metal hydride in the metal hydride reaction vessel 2 means that the metal hydride in the metal hydride reaction vessel 2 and The amount of reaction with hydrogen will be measured.

The resistance change of the resistance wire of the strain gauge 7 is read by a bridge circuit and converted into the amount of reaction between the metal hydride 6 in the metal hydride filling device 1 and hydrogen.

A space of 10 mm was provided between the partition walls 5, and fine particles were activated as metal hydride 6 in a chamber with a volume of approximately 3.1 cm3 .
16.3g of LaNi 5 was filled. In the filled state, the emptiness ratio is approximately 35%, and the apparent specific gravity is increased by applying a little pressure compared to when it is filled without applying force. Hydrogen gas was allowed to flow in and out through the filter 3, and the amount of hydrogen gas flowing in and out was measured using a gas flow meter. A polyimide foil strain gauge B-FAE-5-127 manufactured by Shinko Tsushin Kogyo Co., Ltd. was used as a partition wall displacement detection element and was attached to the partition wall 5. Keep the temperature constant at 25℃ from beginning to end.
Maintain the hydrogen gas pressure at 2.5 atm on both sides of the partition wall 5.
Hydrogen gas was further introduced into the metal hydride filler 1 to cause the metal hydride 6 that did not store hydrogen to store hydrogen, and the amount of strain on the strain gauge 7 was measured. When 0.51N of hydrogen gas newly flows in, the amount of strain on strain gauge 7 is
It was 0.0097. At this time, when calculated assuming that the amount of hydrogen in the gas phase was constant, the amount of reaction between metal hydride 6 and hydrogen (atomic ratio of hydrogen atoms to metal atoms) was 0.2. Similarly, when 0.76N of hydrogen gas is further introduced, the amount of strain is 0.0243 and the amount of hydrogen reaction is 0.5.
Furthermore, the amount of strain when 0.76N of hydrogen gas is injected is
0.0388, and the hydrogen reaction amount was 0.8.
