Primary Cells

  • Can not be recharged. Chemical action can not be reversed.

  • Defect: Polarization: H2 blanketing around electrode.

  • Depolarization agent is added to prevent the H2 blanketing around electrode . Compounds rich in oxygen (i.e. MnO2) are used. The O2 in the depolarization agent combines with H2 to form H2O. (2MnO2 + H2 2MnO3 + H2O):

  • Local Action: Does not contribute to electrical energy.
