Characteristics of Excess Heat in Pd|D2O+D2SO4 Electrolytic Cells Measured by Seebeck Envelope Calorimetry
نویسنده
چکیده
Pre-electrolysis at the boiling point in open Pd|D2O cells is an effective method to activate a palladium cathode, which can produce excess power in subsequent electrolysis in closed systems for several months. The reproducibility is 23/45. Another characteristic of excess heat is the apparent resistance of electrolytic cell changes irreversibly with temperature.

EXCESS HEAT REPRODUCIBILITY AND EVIDENCE OF ANOMALOUS ELEMENTS AFTER ELECTROLYSIS IN Pd|D2O+H2SO4 ELECTROLYTIC CELLS
Electrolyte temperature is a key factor in excess heat production using Pd|D2O+H2SO4 electrolytic cells. Best results are obtained when the electrolyte temperature is close to the boiling point. Stable excess heat is generated by events on or near the Pd cathode surface. In addition to the stable excess heat, heat bursts are sometimes observed. These occurred most frequently in experiments usin...
متن کاملSeebeck Envelope Calorimetry with a Pd|d2o+h2so4 Electrolytic Cell
Anomalous excess heat in Pd|D2O+H2SO4 electrolytic cells was confirmed using an accurate method of heat measurement, Seebeck Envelope Calorimetry. A cell was placed in the calorimeter, which measures the output heat flux directly and avoids many of the problems other methods have. The maximum excess power thus far was 1.3 W (or 11 W cm3) with input power of 13 W at a current density of 0.4 A c...

Excess heat was observed in the Pd|D2O electrolytic system using a Calvet type microcalorimeter. It was found that the average excess power was 0.025 W over 79 hours period. This result corresponds to a volume excess power of 8.75 W /cm Pd or a surface excess power of 0.044 W /cm Pd, and a specific excess heat of 2.48 MJ/cm Pd or 228 eV/atom Pd. The current density and D/Pd ratio for excess pow...

Excess energy was measured with a Seebeck envelope calorimeter in an electrolytic system containing a 2 mm diameter Pd tube cathode. After about 50 hours of electrolysis, many power pulses (Pex < ∼0.5 W) and bursts (Pex > ∼0.5 W) of excess power Pex were observed. The distribution of the number of power pulses N(Pex) with definite excess power Pex plotted on a logarithmic scale is expressed as ...
