These devices are contrasted with a type of cell in which an external current drives a reaction that would not occur spontaneously, electrolytic cells.
One of these devices invented by John Daniell uses zinc, copper, and their solutions. The voltage of this device times the number of moles of transferred electrons times the Faraday constant gives the energy yield of these devices, which consist of two different metals connected by a salt bridge. These devices are contrasted with a type of cell in which an external current drives a reaction that would not occur spontaneously, electrolytic cells. For 10 points, name this type of electrochemical cell capable of generating current and named for an Italian.
