MEMBRANE-ELECTRODE ASSEMBLY FOR ELECTROOSMOTIC PUMP, ELECTROOSMOTIC PUMP INCLUDING SAME, AND FLUID PUMPING SYSTEM

摘要

Provided are a membrane-electrode assembly for an electroosmotic pump, an electroosmotic pump including the membrane-electrode assembly for an electroosmotic pump, and a fluid pumping system including the electroosmotic pump, the assembly comprising: a first electrode which has a porous structure and comprises a first electrochemical reactive material, and to which (+) or (-) voltage is applied; a first membrane, which is provided on one surface of the first electrode, has a porous structure and has a (+) or (-) surface potential; a second electrode which is provided on one surface, opposite to the first electrode, of the first membrane, has a porous structure, and comprises a second electrochemical reactive material, and to which voltage having a polarity opposite to that of the first electrode is applied; a second membrane, which is provided on one surface, opposite to the first membrane, of the second electrode, has a porous structure and has a surface potential having a polarity opposite to that of the first membrane; and a third electrode which is provided on one surface, opposite to the second electrode, of the second membrane, has a porous structure, and comprises a third electrochemical reactive material, and to which voltage having the same polarity as that of the first electrode is applied.
