What is Galvanic Cell?
An electrochemical cell that converts chemical energy from a spontaneous redox reaction into electrical energy. Also called a voltaic cell. Consists of two half-cells connected by a salt bridge. The anode (negative) undergoes oxidation; the cathode (positive) undergoes reduction.

An electrochemical cell that converts chemical energy from a spontaneous redox reaction into electrical energy. Also called a voltaic cell. Consists of two half-cells connected by a salt bridge. The anode (negative) undergoes oxidation; the cathode (positive) undergoes reduction.
Galvanic cells are the basis of all batteries (primary cells like zinc-carbon and alkaline, secondary cells like lead-acid and lithium-ion), fuel cells, and corrosion cells. Standard electrode potentials are measured using galvanic cell arrangements vs. the standard hydrogen electrode (SHE).
Galvanic cells in batteries can short-circuit, overheat, and cause fires or explosions. Lithium metal cells react violently with water. Lead-acid batteries produce H₂ during charging — ensure ventilation. Never short-circuit any battery. Electrolyte solutions (H₂SO₄, KOH) are corrosive.
