Electrochemical cells differ from electrolytic cells in that Electrochemical cell potentials are positive and electrolytic cell potentials are negative Electron flow is from anode to cathode in electrochemical cells and from cathode to anode in electrolytic cells Anions migrate to the anode in electrochemical cells and to the cathode in electrolytic cells Cations migrate to the cathode in electrochemical cells and to the anode in electrolytic cells
