WebKey Points. • An electrochemical cell, also called galvanic or voltaic cell, is a device that produces an electric current from energy released by a spontaneous redox reaction in two half-cells. • The anode will undergo oxidation (loss of electrons) and reduction (gain of election) will happen at cathode. • Electrons leave the metal of ... In chemistry, a cathode is the electrode of an electrochemical cell at which reduction occurs. The cathode can be negative like when the cell is electrolytic (where electrical energy provided to the cell is being used for decomposing chemical compounds); or positive as when the cell is galvanic (where chemical reactions are used for generating electrical energy). The cathode supplies electrons to the positively charged cations which flow to it from the electrolyte (even if the cell is …
