Electrochemical properties of a zinc/polyvinyl alcohol-potassium hydroxide/carbon cell have been investigated. In this cell, PVA-KOH gel has been used as an electrolyte with PVA/KOH wt.% ratio of 60:40, while zinc and carbon rods served as electrodes. The cylindrical glass vessel of length 3.0 cm and of diameter 2.0 cm has been used as a cell compartment. The current-voltage characteristics and open circuit voltage-time, charge voltage/current-time and discharge voltage/current-time studies have been done. The open circuit voltage has been observed for 160 h. It has been found that the cell shows stability and is rechargeable, too.
