Electrolysis in Pd-LiOD(H), NaOD(H) and KOD(H) systems was carried out to clarify the specific role of the lithium for tremendously high density and the dynamic movement of the deuterium on the surface of the Pd cathode. Only for LiOD system with pulse mode current electrolysis, anomalous high density of deuterium and lithium and the dynamic movement of deuterium are observed on the surface of ...

Excess heat was produced at the rate of about 1.2 watts during electrolysis of heavy water with a titanium cathode weighing 0.0625 g. Analysis of the electrodes before and after electrolysis with a scanning electron microscope (SEM) and an energy dispersive spectrometer (EDS) revealed that new surface topographical features with concentrations of unexpected elements (S, K, Ca, V, Cr, Fe, Ni, an...

The energy shift towards carbon-free solutions is creating an ever-growing engineering interest in electrolytic cells, i.e., devices to produce hydrogen from water-splitting reactions. Among the available technologies, Proton Exchange Membrane (PEM) electrolysis most promising candidate for coping with intermittency of renewable sources, thanks short transient period granted by solid thin elect...
