Electrochemical Calorimetric Experiments using Palladium-Boron Cathodes

Authors: Melvin H. Miles

Palladium-Boron (Pd-B) cathodes prepared at the U.S. Naval Research Laboratory have produced electrochemical excess power effects using D2O+ LiOD electrolytes in nearly every experiments conducted at four different laboratories and using four different types of calorimeters. The one failure was due to a structural defect in the Pd-B cathodes. An unusual result is the early appearance of the excess power effect for Pd-B cathodes. Two other research groups have also found excess power effects using these Navy Pd-B cathodes. Possible important factors for Pd-B electrodes are the removal of oxygen by the boron during processing, the increased mechanical strength versus pure palladium, less volumetric expansion of these electrodes during loading with deuterium, and the much slower escape of deuterium from this cathode. The history of this research by the U.S. Navy laboratories for these Pd-B materials and the resulting government reports are presented.

Comments: Pages. Research by U.S. Navy laboratories led to Pd-B materials that produce the Fleischmann-Pons excess power effect in nearly every experiment. Email:
