PURPOSE: To achieve higher probability of generation of normal temperature nuclear fusion and a promotion of reaction by a method wherein the surface of a plating type electrode vibrator is plated with a nuclear fusion generating substance and a vibrating body is used being resonated as electrode to expand a reaction area and a reaction speed.

CONSTITUTION: The apparatus is set on a deuterium tank 18 and a positive lectrode 8 for electrolyte is mounted. When a magnetostrictive vibration is caused starting an electrolysis with a power source 14 for electrolyte. deuterium or a hydrogen gas is generated and gathered to a gas reservoir 19 from the surface of a vibration type negative electrode 1 having a pure nickel plate plated with palladium or titanium. An oxygen gas is generated and gathered to a gas reservoir 20 from the positive electrode 8. At the same time, a normal temperature nuclear fusion is caused to generate a large amount of heat. The deuterium heated comes out of a circulation water outlet 21 and the heat energy thereof is utilized with a heat exchanger 22. The deuterium cooled returns to the deuterium tank 18 from a circulation water inlet 24. Since the electrode plated directly with the palladium and titanium as fusion reaction substance is employed as vibrator, the loss in the transmission of vibration is limited thereby promoting normal temperature nuclear fusion.
