WebVoltaic Cells A Voltaic cell is a device which physically separates the reduction half of a redox reaction from the oxidation half and results in a flow of electrons through the circuit. Each compartment of a voltaic cell is termed a half-cell. The half-cell that serves as the site for reduction contains the cathode electrode, WebVoltaic Cells. An electrochemical cell which causes external electric current flow can be created using any two different metals since metals differ in their tendency to lose electrons. Zinc more readily loses electrons than …
