Abstract

The present disclosure provides an apparatus and a method for manufacturing a continuous reactor type core-shell catalyst electrode, which may manufacture a large amount of continuous reactor type core-shell catalyst electrodes by improving coating efficiency of shell metal by using reaction chambers disposed in a circular shape or in a line. The apparatus for manufacturing a continuous reactor type core-shell catalyst electrode according to one exemplary embodiment of the present disclosure includes: a main body which is provided with a fixed shaft inside thereof and an upper portion of which is opened and closed by being detached from or attached to the fixed shaft; reaction chambers which are disposed plurally in a circular shape inside the main body, store reaction solution inside thereof, are equipped with movable members and counter electrodes, and a lateral portion of which is coupled with a reference electrode; a power transmission member which transmits power to the movable member; a palladium sheet which is moved by the movable member and immersed in the reaction solution as the movable member moves downward; a power supply which applies a voltage to the electrodes; and a solution injection member which injects a copper precursor-containing solution or a platinum precursor-containing solution into the reaction solution.

the reaction chamber comprises: a first reaction chamber in which the counter electrode is installed inside thereof, the reference electrode is coupled to the lateral portion thereof, the palladium sheet, which is moved by the movable member and immersed in the reaction solution, is reduced, and then the reduced palladium sheet is coated with copper; and a second reaction chamber in which the cooper-coated palladium sheet, which is moved from the first reaction chamber by the movable member and then immersed in the reaction solution, is coated with platinum.

3 . The apparatus of claim 2 , wherein
the first reaction chamber is characterized in that the power supply provides electric potential which is higher than power for copper oxidation, for the electrode which is installed inside the first reaction chamber and coupled thereto, allowing coating the reduced palladium sheet.

4 . The apparatus of claim 2 , wherein
the first reaction chamber is characterized by accommodating a porous block which is composed of a metal mesh to be contacted with the palladium sheet which is moved downwardly by the movable member.
