A redox reaction is reversed
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.
Electrons flow in the opposite direction.
In an electrolytic cell, electrical energy is used to drive a non-spontaneous reaction, causing a chemical change. In contrast, a galvanic cell generates electrical energy from a spontaneous chemical reaction. Electrolytic cells are often used in processes like electrolysis, while galvanic cells are used in batteries.
In an electrochemical cell (galvanic cell), the cathode is positive because it is where reduction occurs, attracting cations from the electrolyte. Conversely, in an electrolytic cell, the cathode is negative because it is connected to the external power source, which forces electrons into the electrode, facilitating reduction at that terminal. Thus, the polarity of the cathode changes depending on the type of cell and the direction of the current flow.

The significance of anode polarity in electrochemistry is that it determines the direction of electron flow in a galvanic cell or electrolytic cell. The anode is where oxidation occurs, and it is positively charged in a galvanic cell and negatively charged in an electrolytic cell. This polarity affects the overall reaction and the flow of ions in the cell.
