Electrochemical cell comprising channel-type flowable electrode units

A channel-type flow-electrode unit comprising:

• a channel-type liquid-permeable wall confining the structure of the electrode unit as a scaffold;
• an ion-exchangeable material applied to an inner surface or an outer surface of the channel-type liquid-permeable wall, the liquid-permeable wall itself, or a combined position thereof to allow a positive ion or a negative ion to pass therethrough;
• a porous current collector applied to an inner surface of the liquid-permeable wall to which the ion-exchange material has been applied;
• and
• an electrode flow channel separated from the liquid-permeable wall by the porous current collector, along an inside of which an electrode active material-containing fluid introduced from a channel inlet and discharged to a channel outlet flows.
