A Galvanic cell, or Voltaic cell, named after Luigi Galvani, or Alessandro Volta respectively, is an electrochemical cell that derives electrical energy from spontaneous redox reaction taking place within the cell. It generally consists of two different metals connected by a salt bridge, or individual half-cells separated by a porous membrane.
Volta was the inventor of the voltaic pile, the first electrical battery. In common usage, the word "battery" has come to include a single Galvanic cell, but a battery properly consists of multiple cells.

Famous quotes containing the words galvanic and/or cell:
“Come, walk like this, the dancer said,
Stick you your toesstick in your head,
Stalk on with quick, galvanic tread
Your fingers thus extend;
The attitudes considered quaint,”
—Sir William Schwenck Gilbert (18361911)
