While nickel rods were used initially, recent experiments used nickel powder (particle size is said to be in the nm-range, the patent application mentions 10 µm). Rossi mentions "Gerli Metalli" company<ref>Powder nickel: Gerli Metalli--Milan</ref> from Milan as their supplier. Furthermore, unknown catalysts, not specified even in the patent application, are said to be employed. Nickel oxide - which reacts with hydrogen creating water and heat (NiO2 + H2 --> Ni + H20) – allegedly was not used. According to the patent application, an inner water circuit (with a boric acid solution) is placed inside of the reactor, heat is transferred to an external water circuit by a heat exchanger.

By heating with electrical energy, protons from hydrogen gas are said to enter the nickel atoms at 180-400 degrees Celsius and lead to a nuclear reaction if pressure was increased strongly at regular intervals. Altogether, hydrogen is said to be consumed and some helium is generated.<ref>S. Focardi, V. Gabbani, V. Montalbano, F. Piantelli, S. Veronesi. "''Large excess heat production in Ni-H systems''". Il Nuovo Cimento Vol. 111 A, N.11 pp. 1233, novembre 1998</ref> The nickel rod is said to show tiny surface craters after a reaction. According to the patent application, the electrical pre-heating will be turned off automatically by a thermostat when a certain operating temperature is achieved. Further electrical energy (20 to 80 W) was only necessary to supply control electronics. The modules controlling the heating resistors are 12 phase fired controllers of the type VL676 from company GSEI in Genua<ref>http://www.gsei.it/attachs/P020_01.pdf</ref> They can be, depending on type, regulated by 10 or 20 A in 20 half-steps (0..9) and have a consumption of 2 watts (in sum 24 W) from a 24 V voltage source. Internet rumours which cannot be verified claim that high voltage or a magnetic field of 360 kV to overcome the [http://de.wikipedia.org/wiki/Coulomb_barrier Coulomb barrier] might be applied. The application of so high a voltage is not possible within such a small device due to spark generation.
