The state of the palladium metal has been identified on the basis of statistical data to play fundamental roles in producing the Fleischman-Pons excess heat effect. The deuterium loading dynamics and its equilibrium concentration are mostly controlled by the metallurgy; a minimum threshold loading (D/Pd ∼ 0.9) is necessary to observe the excess. The crystallographic orientation is also correlated with the phenomenon such that mainly (100) oriented samples gave the highest reproducibility. A specific cathode surface morphology, identified by means of the power spectral density function, represents an additional identified condition to observe the effect. Materials specimens respecting the characteristics described above have been used to obtain a transportable reproducibility. Designed materials giving excess power have been produced but the amplitude of the signals and full reproducibility are not yet achieved. Other features of the material such as the nature and content of impurities and defects seems to be crucial in obtaining the required palladium characteristics. © 2012 ISCMNS.
