WebGalvanic (or voltaic) cells use a thermodynamically favored redox reaction to generate an electric current. Each half-reaction takes place in a separate compartment, or half-cell, containing an electrode. The electrode where oxidation occurs is the anode, and the electrode where reduction occurs is the cathode. WebThe cathode is the electrode where reduction (gain of electrons) takes place (metal-B electrode); in a galvanic cell, it is the positive electrode, as ions get reduced by taking up electrons from the electrode and plate out (while in electrolysis, the cathode is the negative terminal and attracts positive ions from the solution).
