         1 . A device for electrowinning europium using a channeled cell, the device comprising:
 a cathode cell including a channel having an inlet and an outlet;   an anode cell including a channel having an inlet and an outlet; and   an ion-exchange membrane tightly interposed between the cathode and anode cells,   wherein reduced europium is exhausted from the outlet of the cathode cell.   
     
     
         2 . The device of  claim 1 , wherein at least one bead for generating a turbulent flow is formed on each inner surface of the channels of the cathode and anode cells. 
     
     
         3 . The device of  claim 1 , wherein a quantity of electric charge applied to the cathode and anode cells is 110% or more when the quantity of electric charge is substituted into a value obtained by dividing a quantity of applied electric charge by a theoretical quantity of electric charge. 
     
     
         4 . The device of  claim 1 , wherein the cathode and anode cells include graphite. 
     
     
         5 . The device of  claim 1 , wherein a sectional shape of the channel is one of a rectangular shape, a U-shape, and a V-shape. 
     
     
         6 . The device of  claim 1 , wherein an electrowinning solution input to the inlet flows at Reynolds number of 2000 or more. 
     
     
         7 . The device of  claim 1 , wherein a solution containing Eu 3+  is input to the inlet of the cathode cell, and
 a solution containing Fe 2+ , which is able to p-react with the solution containing Eu 3+  input to the cathode cell, is input to the inlet of the anode cell. 
 
     
     
         8 . The device of  claim 2 , wherein at least one bead for generating the turbulent flow is installed per a unit length of the channel.
