In Fig. 10.2b, a battery or other voltage source is used to force a current through the cell in the opposite direction from the spontaneous reaction in the short-circuited cell. Reaction (10.1) now proceeds from right to left and the positions of the cathode and anode in the cell are reversed. This electrolytic cell mode of operation is commonly employed in practical applications of aqueous electrochemistry (e.g., to produce H2 and O2 by electrolysis of water).
