Evidence for Excess Energy in Fleischmann-Pons-Type Electrochemical Experiments

The production of excess energy in palladium cathodes electrochemically loaded with deuterium (the Fleischmann-Pons Experiment) has been debated in the literature since its first publication in 1989. In a subset of 61 trials, we electrochemically loaded palladium-rhodium foil cathodes with deuterium from alkaline solutions of heavy water in specially designed closed calorimeter cells. We observed excess energy bursts in the range 2.4-44.3 kJ in 6% of these experiments. Additionally, a conservative estimate of the total integrated output energy is greater than the total integrated input energy in these experiments. This paper documents the steps taken to examine these results thoroughly for calibration/measurement errors and instrumental artifacts. A 2.4 kJ energy burst is at least four times greater than the energy released by oxidizing deuterium in the cell headspace. The data and subsequent elimination of alternative explanations for excess energy production lead us to conclude that the excess energy is real and of yet unknown origin. (C) 2014 ISCMNS.
