英文摘要	Hydrogen evolution and dissolution of Aluminium (Al) have been investigated at different anodic potentials in de-oxygenated 3.5 % NaCl electrolyte to afford new insights into its negative difference effect (NDE). Innovatory to previous reports, the instantaneous concentration of dissolved Al3+ ions was detected using a novel in-situ electrochemical ICP-OES technique and a dissolution stoichiometry of n = 3 was observed, thereby precluding the Al intermediate ion mechanism. The effects of the local pH and the surface film's breakdown area on the hydrogen evolution rate were investigated quantitatively, which suggests that the NDE of Al results from the combined effects of these two factors.
