Comparison between electrochemical cell and electrolytic cell

Electrochemical cell	Electrolytic cell
Converts chemical energy to electrical energy	Converts electrical energy to chemical energy
Flow of electrons determined by reactivity of chemical species	Flow of electrons determined by external power supply
Anode is negative, cathode is positive by convention	Anode is positive, cathode is negative by convention
May or may not require a salt bridge
May or may not require separate cells
Oxidation occurs at anode while reduction occurs at cathode
