Electrochemical cell (Galvanic Cell)
A Galvanic cell converts chemical energy into electrical. Here, the redox reaction is spontaneous and is responsible for the production of electrical energy.The two half-cells are set up in different containers, being connected through the salt bridge or porous partition.Here the anode is negative and cathode is the positive electrode. The reaction at the anode is oxidation and that at the cathode is reduction.The reaction at the anode is oxidation and that at the cathode is reduction. They move from anode to the cathode in the external circuit.
Electrolytic cell
An electrolytic cell converts electrical energy into chemical energy. The redox reaction is not spontaneous and electrical energy has to be supplied to initiate the reaction. Both the electrodes are placed in a same container in the solution of molten electrolyte. Here, the anode is positive and cathode is the negative electrode. The electrons are supplied by the species getting oxidized. The external battery supplies the electrons. They enter through the cathode and come out through the anode.
