Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for occluding and containing deuterium in a metal capable of occluding deuterium, and a method for causing a cold fusion reaction by occluding and storing deuterium.

[0002]

2. Description of the Related Art Conventionally, cold fusion which causes nuclear fusion by electrolyzing heavy water is generally carried out by electrolyzing Pd as a cathode and Pt as an anode in a heavy water electrolytic solution containing LiOD as an electrolyte. is there.

By the way, this method can occlude deuterium in Pd by electrolyzing heavy water. However, if the current density is lowered or electrolysis is stopped, the deuterium occlusion rate is lowered.
Furthermore, when Pd that has occluded deuterium is taken out of the electrolytic solution, deuterium is released to the outside of Pd, and the occlusion rate further decreases. The lowering rate is faster as the storage rate is higher.

[0004]

SUMMARY OF THE INVENTION Therefore, the present invention provides a deuterium confinement method that absorbs deuterium and that can be taken out of the electrolytic cell while maintaining a high storage rate. It is intended to provide a cold fusion method capable of easily causing a nuclear fusion reaction by using an occluded metal.

Means for Solving the Problems The method for confining deuterium of the present invention for solving the above-mentioned problems is as follows. After deuterium electrolysis is performed by deuterium electrolysis using an electrode made of a deuterium storage metal as a cathode, It is characterized by forming a deuterium-impermeable barrier layer on the cathode surface by electrolytic or electroless plating. Deuterium storage metals include Pd and P
D alloy, Ti, Ti alloy, and other hydrogen storage metals are preferable. As the barrier layer, Hg, Au, Ag, C
u, Sn, In, Zn and the like are preferable. Further, the cold fusion method of the present invention is characterized by causing a deuterium-occluded metal obtained by the deuterium confinement method described above to have a local temperature difference to cause a fusion reaction. In this cold fusion method, in order to make a temperature difference between the metals that have occluded deuterium, it is preferable to perform the heating under a pressure higher than atmospheric pressure.

[0006]

As described above, the deuterium confinement method of the present invention stores deuterium in the electrode (cathode) of the deuterium storage metal by heavy water electrolysis, and the electrode (cathode) surface is subjected to electrolytic or electroless plating. Since the barrier layer is impermeable to hydrogen, even if the electrode (cathode) of the deuterium storage metal is taken out of the electrolytic cell, the stored deuterium is not released to the outside. In particular, heavy water electrolysis stabilizes even when the number of stored hydrogen atoms per Pd atom is 0.9 or more.

Further, in the cold fusion method of the present invention, since a deuterium storage metal containing deuterium has a local temperature difference as described above, local deuterium atoms are locally concentrated. Cold fusion reaction is easily generated.

EXAMPLE An example of the deuterium containment method of the present invention will be described. As shown in Fig. 1, 50 mm in length and 50 in width in the electrolytic cell 1.
mm Pd plate 2 with a thickness of 1.5 mm is used as a cathode, and Au lead wire 3 with a wire diameter of 0.5 mm that does not allow deuterium to pass through is attached to the cathode. Also, in the electrolytic cell 1, a Pt wire is provided around the Pd plate 2. 4 was placed as an anode, and heavy water containing 1 M D ₂ SO ₄ was used as an electrolytic solution 5 for electrolysis. In addition, 6 is a gas diffusion film, which has a catalytic action for returning decomposed O ₂ and D ₂ to D ₂ O, and the structure of the film 6 is such that the reaction layer is on the outside and the gas diffusion layer is on the inside. It was arranged for. At the initial stage of electrolysis, the solution temperature was controlled to 40 ° C., electrolysis was carried out at 150 mA / cm ² for 20 hours, and then electrolysis was carried out at 500 mA / cm ² for 24 hours. After that, anodic polarization was performed, and the deuterium stored in the Pd plate 2 was oxidized to obtain a deuterium storage rate, which was 0.84. After deuterium was occluded in the Pd plate 2 again by the same operation as described above, 1 mM of Hg ion was added to the electrolyte solution 5. Then, when the electrolysis was stopped after 30 minutes, normally the stored deuterium was released as bubbles from the cathode surface, but it was not released at all, and Hg was deposited on the cathode surface of the Pd plate 2, that is, Hg by electrolytic plating. It was confirmed that the barrier layer was formed. It was stable even when taken out from the electrolyte solution 5 into the atmosphere, had no weight change even after being left for 10 days, and a decrease in deuterium occluded was not observed. Similarly, Au, Ag, Cu, Sn, In, Zn
Even when a barrier layer made of a metal such as Pd was formed, a decrease in deuterium occluded in the Pd plate 2 was not observed. It has been found that the barrier layer can be formed well by adding a plating leveling agent to the electrolytic solution 5.

Next, Pd containing deuterium as described above is contained.
An embodiment of the cold fusion method of the present invention using the plate 2 will be described. As shown in FIG. 2, while the Pd plate 2 containing deuterium is fitted in the ceramic packing 7 having a thickness of 1.6 mm, the Pd plate 2 is sandwiched while being pressed by the two Cu jigs 8 and 8 ′.
When the cooling water is circulated through the passage 9 of the one Cu jig 8 to cool it and the other Cu jig 8'is heated by the heater 10 to make a temperature difference in the thickness direction of the Pd plate 2, Local deuterium atoms were locally concentrated, cold fusion occurred, and excess heat was observed.

In the above embodiment, the shape of the cathode is a plate,
It may be spherical, columnar, or cylindrical. Further, although the lead wire 3 is Au, the lead wire 3 is not limited to this, and any material that does not transmit deuterium and has good electric conductivity may be used. Further, ions such as Al may be added to the electrolytic solution 5 for the purpose of increasing the storage rate of deuterium. Further, the anode is not limited to metal, but may be a gas diffusion electrode or a porous electrode. In addition, the counter electrode reaction may be oxygen generation, deuterium oxidation, ionization reaction of zinc, aluminum or the like.

Further, as means for making a temperature difference in the thickness direction of the Pd plate 2, in addition to the embodiment, gas (helium gas etc.) which is a heat medium, liquid (pure water) and solid (silver) are contacted. There are means such as applying light and applying light (electromagnetic waves). Further, the jig for sandwiching the Pd plate 2 is not limited to Cu, and other metals or ceramics may be used.

As can be seen from the above description, according to the method for confining deuterium of the present invention, the barrier layer can be formed on the cathode in which deuterium is occluded, so that the state of high occluding rate can be maintained. Further, according to the cold fusion method of the present invention, since a deuterium-occluded sample can have a local temperature difference and the deuterium concentration can be increased on the low temperature side, a nuclear fusion reaction easily occurs. be able to.
