A galvanic cell is a type of electrochemical cell that generates electricity through chemical reactions. The type of chemical reactions that occur in galvanic cells are known as spontaneous redox reactions, which are reduction-oxidation reactions that release energy. Galvanic cells usually contain two types of metal, which undergo reduction and oxidation reactions in separate chambers. A porous membrane or salt bridge joins the two metals, permitting electrons to flow as the redox reactions occur. The resultant electricity can then be harnessed to perform tasks and work that require external energy input. Batteries often contain one or more galvanic cells where their electricity is produced. |
