Abstract
The anodic dissolution of aluminum in the KOH ethanol solutions is considered. It is shown that an addition of gallium and indium compounds to the 2 M KOH solution in 96% ethanol leads to an abrupt increase in the anodic dissolution current of aluminum near the open-circuit potential and its shift by 300 mV toward negative values. The discharge galvanostatic curves in the solutions with the additives of gallium and indium compounds contain a flat discharge plateau at the current densities up to 4 mA/cm2. The hydrogen evolution rate in a number of KOH ethanol solutions is measured.
