چکیده

A twin system for hydrogen-isotope absorption experiments has been constructed to replicate the phenomenon of heat and He generation during D2 gas absorption in nano-sized Pd powders reported by Arata and Zhang, and to investigate the underlying physics. For PdZr oxide nano-powders, anomalously large energies of hydrogen isotope absorption, 2.4 0.2 eV/D-atom and 1.8 0.4 eV/H-atom, as well as large loading ratios of D/Pd =1.1 0.0 and H/Pd =1.1 0.3, respectively, were observed during deuteride/hydride formation. The sample charged with D2 also showed significantly positive output energy in the second phase after deuteride formation. Results for 0.1-mPd powder samples and Pd-black samples are also shown, for comparison.

Deuterium Gas Charging Experiments with Pd Powders for Excess Heat Evolution ( II ) Discussions on Experimental Results and Underlying Physics

Experimental results obtained for Pd/PdO/ZrO2 nano-composite samples are summarized and the underlying physics is discussed. Arata-Zhang’s May 2008 excess heat result was replicated quantitatively. Using Pd/PdO/ZrO2 powders (produced by Santoku Co., Kobe Japan), we obtained: 1) D-gas charge in the first phase (zero pressure interval) gave 20~90% excess heat than H-gas charge. 2) In the second p...

Hydrogen Absorption Property of Pd-Doped Porous Materials

In electrochemical loading of Pd with deuterium, it has been known that attaining a D/Pd value larger than 0.88 is necessary for triggering excess heat effects [1]. It has been reported by Arata and Zhang that the heat arising from D-D nuclear fusion reaction in solid is observed simply by pressurizing nano-Pd/ZrO2 system with deuterium gas [2]. It seems that nano-scale Pd particles absorb more...

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...

Calorimetric Studies of Palladium Alloy Cathodes Using Fleischmann-Pons Dewar Type Cells

My first three experiments conducted at NHE using the Fleischmann-Pons (F-P) Dewar type cells investigated the Pd-Ce-B, Pd-B, and Pd-Ce alloy cathodes. Significant excess power was produced from the cells using the Pd-B and Pd-Ce alloy cathodes. The Pd-Ce-B alloy, in contrast, showed no measureable excess power effects. Previous experiments at China Lake using similar Pd-B alloy cathodes prepar...
