A voltaic cell is an electrochemical cell that uses a chemical reaction to produce electrical energy. 1  The anode is an electrode where oxidation occurs. 2  The cathode is an electrode where reduction occurs.  A salt bridge is a chamber of electrolytes necessary to complete the circuit in a voltaic cell.
Electrochemical cells which generate an electric current are called voltaic cells or galvanic cells, and common batteries consist of one or more such cells. In other electrochemical cells an externally supplied electric current is used to drive a chemical reaction which would not occur spontaneously.or a battery, this is the positive terminal. In order for the voltaic cell to continue to produce an external electric current, there must be a movement of the sulfate ions in solution from the right to the left to balance the electron flow in the external circuit.
