Cold Fusion: Advances in Condensed Matter Nuclear Science, Volume , 14 January 2020,
Long-term electrolysis with a thick Pd electrode in 0.1. M LiOD was performed. Some techniques to conduct clean and stable electrolysis are described. The surface morphology of postelectrolysis Pd electrodes was analyzed: it consisted of holes and two long faults without any crack. To understand the evolution of the morphology, the physicochemical properties of hydrated Pd have been studied by in situ potentiometric, resistance, and dilatometric measurements. The results of microstructural changes were further analyzed with reference to knowledge of hydrogen embrittlement. The sample preparation and electrolysis method necessary to accomplish reproducible cold fusion experiments are presented.
