Electrolytic cell
A galvanic cell can become an electrolytic cell by applying an external voltage that is of opposite polarity to the cell's spontaneous voltage. This external voltage can overcome the natural tendency of the cell to generate electricity and drive a non-spontaneous chemical reaction in the reverse direction, converting it into an electrolytic cell.

In an electrolytic cell
Reduction occurs at the cathode in an electrolytic cell.
Diagram of electrolytic cell
In an electrolytic cell, the anode is positive.
In an electrolytic cell, the anode is designated as positive.
In an electrolytic cell with nickel and copper electrodes, nickel at the anode gets oxidized, losing electrons to form nickel ions. The copper electrode at the cathode gains electrons and gets reduced, forming copper metal. This process allows for the transfer of nickel ions from the anode to the cathode.
