摘要：
The present disclosure is directed to an electrochemical cell, preferably a zinc air cell, with improved voltage and reduced polarization. The combination of an anode corrosion inhibitor with a surfactant system yields enhanced cell voltage and capacity for the cell that are above the individual contributions of the corrosion inhibitor and the surfactant system. The surfactant system comprises a hexyl diphenyl oxide disulfonic acid surfactant and at least one amphoteric surfactant.
