Chemical Reactions and Isotopes

Starting from papers by Fleischmann and Pons, many investigators have found the excess power effect during a heavy water electrolysis. They connected this effect with the deuterons "cold fusion". A significantly larger number of investigators did not have found this effect, so they do not agree with the proposed explanation and consider the results of Fleischmann and Pons being a mistake or an instrumental artifact. In this paper experimentally proved that the Fleischmann-Pons effect (of burst type) is caused by an exothermic reaction of a recombination of the atomic deuterium accumulated in electrodes during electrolysis of the electrolyte. This reaction is similar to the reaction of thermal runaway in electrochemical batteries with aqueous electrolyte. Thus experimentally proved that the Fleischmann-Pons effect is not associated with cold fusion of deuterium nuclei. While the Fleischmann-Pons effect (of the weak type) is due to a partial recombination of the deuterium and the oxygen, i.e. in this case the excess power is apparent or imaginary. It is shown that the established mechanism of Fleischmann-Pons effect explains all the currently known experimental facts. The recommendations are given allowing a reproduction of this effect without a failure.
