A dry cell is a compact form of LeClanche cell. It consists of an outer container made of inc, which acts as anode. The zinc container is lined from inside with a porous insulating paper.
The cathode is a carbon rod having a brass cap. The zinc container lined from inside with a porous insulating paper. The space between the cathode and anode is filled with a mixture of MnO2 and a thick paste of ammonium chloride, (NH4Cl), zinc chloride (ZnCl2), and charcoal. The porous paper lining prevents a direct contact between zinc container and the paste, and acts as a salt bridge.
