Abstract
Corrosion is reduced in aqueous electrochemical cells having zinc anodes comprised of single crystal zinc particles by the addition of small amounts of a gas inhibiting surfactant, for example, an organic phosphate inhibitor such as RA600 from GAF Corp. to the cell. A synergistically lowered rate of corrosion and cell gassing is obtained even with reduction of mercury content.
