Measurements of excess heat from a Pons-Fleischmann type electrolytic cell using palladium sheet
Two pieces of palladium sheet were loaded with deuterium in a Pons-Fleischmann type electrolytic cell and measurements were made of heat production. One sheet produced a steady increase in excess power that reached 7.5 watts (20% of input power) before the study was interrupted. A second similar sheet from a different batch of palladium did not produce any measurable excess power. There was a difference between the loading behavior, the maximum stoichiometry, and the presence of excess volume in the deuteride made from these materials. The first sheet contained 0.8% excess volume after deloading from D/Pd=0.82 to D/Pd=0.73, and the second sheet contained 13.5 % excess volume while at D/Pd=0.75. The high excess volume in the latter case is an indication of internal cracks.
