Expert Answer:

The term polarization as used in case of cells refers to decrease in potential difference betweeen the plates.

In a cell, if the current is drawn in the external circuit for some time, the potential difference between the two plates generally decreases.This is due to the formation of layer of hydrogen bubbles on positive plate . This layer prevents the flow of further hydrogen towrds it .This results in decrease in potential difference betweeen the plates. This defect is called polarization.
