Electrolytic cell, an Uncommon card

The card carries these facts from its Wikipedia article.

• In the cell, a voltage is applied between the two electrodes, an anode and a cathode, immersed in an electrolyte solution.
• This contrasts with a galvanic cell, which produces electrical energy from a spontaneous chemical reaction and forms the basis of batteries.
• The net reaction in an electrolytic cell is a non-spontaneous, whereas in a galvanic cell, it is spontaneous.
