Abstract
A surfactant is present in an aqeuous alkaline electrolyte of a consumable metal anode electrochemical cell in a concentration sufficient to substantially reduce both the surface tension of the electrolyte and the rate of the parasitic corrosion reaction occurring between the electrolyte and the anode. The surfactant is useful in minimizing the harmful side effects, such as increased heat generation, anode consumption without producing useful energy and increased hydrogen gas production rates, such as are associated with the parasitic corrosion reaction experienced in such electrochemical cells.
