Abstract
An electro-osmotic pump using a reversible electrode reaction is provided, the electro-osmotic pump using a reversible electrode reaction comprising: a membrane that allows movement of a fluid; and first and second electrodes that are arranged on both sides of the membrane, respectively, and composed of a porous material or structure to allow the movement of the fluid, and a material to cause a reversible electrochemical reaction, wherein the first and second electrodes are alternately and reversely supplied with a voltage to make the electrochemical reaction repeat alternately forward and backward, and as a result, the alternate change of the movement direction of the fluid generates a pumping force to repair the first and second electrodes.

An electro-osmotic pump using a reversible electrode reaction, comprising:
- a membrane that allows movement of a fluid;
- and
- first and second electrodes that are arranged on both sides of the membrane, respectively, and composed of a porous material or structure to allow the movement of the fluid, and a material to cause a reversible electrochemical reaction,
- wherein the first and second electrodes are alternately and reversely supplied with a voltage to make the electrochemical reaction repeat alternately forward and backward, and as a result, the alternate change of the movement direction of the fluid generates a pumping force to repair the first and second electrodes.
(canceled)
A fluid pumping system, comprising:
- an electro-osmotic pump comprising:
- a membrane that allows movement of a fluid;
- first and second electrodes that are arranged on both sides of the membrane, respectively, and composed of a porous material or structure to allow the movement of the fluid and a material to cause a reversible electrochemical reaction;
- and a power supply that alternately and reversely supplies a voltage to the first and second electrodes, to provide a pumping force to a transfer target fluid;
- and
- a separator that is provided in at least one end of the electro-osmotic pump to separate the fluid and the transfer target fluid from each other,
- wherein the first and second electrodes are alternately and reversely supplied with a voltage to make the electrochemical reaction repeat alternately forward and backward, and as a result, a suction force and a discharge force are repeatedly delivered to the transfer target fluid through the separator due to the repeated forward and backward movement of the fluid.
