Charging Hydrogen into Ni in Hydride-Containing Molten Salts

Abstract

Elevated-temperature calorimetric measurements were performed using a cell: A1 6061 alloy I LiH(saturated), LiCl-KCl eutectic I Ni with a charging current of about 600 mA. An anomalous positive temperature excursion was observed, which was difficult to explain based on our understanding of the electrochemical reactions occurring in the cell and the associated enthalpies. The potential between the working and counter electrodes fell in two peculiar ranges: in the initial stage, 0.7-1.2V, and the later stage, 2.3-2.6V -- a range of great interest -- due to its similarity to the condition of an excess heat event that we reported in the Pd-D system in which significant excess heat was measured.
