Abstract

A decrease in the excess deformation volume (a kind of “imprint” of the system after the stay of hydrogen in Pd) with an increase in the amount of hydrogen introduced into Pd (starting from H : Pd = 0.25) and then removed electrochemically. In parallel, an increase in the electrical conductivity of electrochemically dihydrogenated palladium hydrides by 12% in comparison with the initial samples of pure palladium in a wide temperature range (75–300 K) was recorded. This means that some of the hydrogen in the Pd (about 5.3 × 1015 atoms per sample) passed into a more compressed, highly conductive phase. In this case, an increase in electrical conductivity with respect to pure Pd can occur both due to the formation and propagation of highly conductive regions of palladium hydride and due to electron transfer (percolation, tunneling) between individual nanoclusters of quasi-metallic hydrogen, localized in the region of metal structural defects, namely, in vacancy clusters and inside the cores of edge dislocations, where the highest pressures in the lattice are achievable.
