Videos of Palladium Hydride Phases

The storage of hydrogen in metals is one way to provide the fuel needed for fuel cells. Palladium (Pd) and its alloys are well-known absorbers of large quantities of hydrogen and the mechanisms of this have been reported here frequently, for instance (1). Now scientists in Ukraine, at the Donetsk State Technical University (2), where the Pd-hydrogen system has been studied for several years, latterly by recording optical microscopy, report video evidence of the mechanism of the generation and growth of the reverse ß→α hydride phase transformation in subsurface layers of Pd ß-hydride at 270–100°C (3).
