DIFFERENT TYPES OF

CELLS

BY :- NAVEEN KUMAR

K V LAKHANPUR

slide2

CELL

CELL IS A DEVICE WHICH

CONVERT CHEMICAL ENERGY INTO ELECTRICAL ENERGY AND VICE VERSA

slide3

TYPES OF CELLS

ELECTROCHEMICAL CELL:A DEVICE WHICH CONVERT CHEMICAL ENERGY INTO ELECTRICAL ENEGRY eg DRY CELL, ,ZINC CADMIUM CELL & FUEL CELL

ELECTROLYTIC CELL:-A DEVICE WHICH CONVER ELECTRICAL ENERGY INTO CHEMICAL ENERGY egDOWNS CELL, CASTNER-KELLNER CELL

The electrolytic cell
  • Electric current forces charges on electrodes

Na+

Na+

Cl–

Cl–

  • Na+ is attracted to negative, Cl– to positive
  • Na+ takes up an electron: Na+(aq) + e– Na
  • Cl– gives up an electron: 2Cl–(aq)  Cl2 + 2e–
  • Thus electricity continues to flow
  • Pure Na is deposited, Cl2 gas is produced
dry cell
Dry cell

At anode

zn-------------------zn2++2e-

At cathode

2 MnO2+2NH4++2e---Mn2O3

+H2O+2NH3( )

NH3 IS CONSUMED IN COMPLEX FORMATION WITH Zn 2+ ION

Zn2++4NH3 ---------------- [Zn(NH3)4}2+ -----------[Zn(NH3)4]Cl2

At anode

Zn-------------------Zn2++2e-

At cathode

2 MnO2+2NH4++2e---Mn2O3

+H2O+2NH3( )

NH3 IS CONSUMED IN COMPLEX FORMATION WITH Zn 2+ ION

Zn2++4NH3 --- [Zn(NH3)4}2+ --------2Cl------[Zn(NH3)4]Cl2

fuel cell
Fuel cell

Cathode: O2(g) + 2H2O(l ) + 4e–⎯→ 4OH–(aq)

Anode: 2H2 (g) + 4OH–(aq) ⎯→ 4H2O(l) + 4e–

OVERALL REACTION

2H2(g) + O2(g) ⎯→ 2 H2O(l )

MERITS OF FUEL CELL

ECO FRIENDLY

CONTINUOUS SOURSE OF ENERGY

HIGH EFFICIENCY

DEMERITS OF FUEL CELL

VERY EXPENSIVE

HEAVY

NOT CONVENIENT TO USE

HIGHLY CORROSIVE NATURE OF THE ELECTROLYTE
