Abstract

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 are provided. The apparatus for manufacturing a continuous reactor type core-shell catalyst electrode includes: a main body; reaction chambers which are disposed plurally in a circular shape inside the main body, store reaction solution inside thereof, are equipped with a movable member and counter electrodes, and are coupled with a reference electrode to a lateral portion thereof; 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.

First claim

What is claimed is:

1. An apparatus for manufacturing a continuous reactor type core-shell catalyst electrode comprising:
a main body which is provided with a support inside thereof and an upper portion of which is opened and closed by being detached from or attached to the support;
reaction chambers which are disposed plurally in a circular shape inside the main body, store reaction solution inside thereof, are equipped with a movable member and a counter electrode, and are coupled with a reference electrode to a lateral portion thereof;
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.

2. The apparatus of claim 1 , wherein the reaction chambers comprise:
a first reaction chamber in which the counter electrode is installed inside thereof, the reference electrode is coupled to the lateral portion thereof, and the palladium sheet, which is moved by the movable member and immersed in the reaction solution, is coated with copper via an underpotential deposition (UPD) by applying a potential to the counter electrode and the reference electrode with the power supply, wherein the potential is higher than a redox potential of copper; and
a second reaction chamber in which a copper-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 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.

4. The apparatus of claim 2 , wherein the second reaction chamber is characterized in that the copper-coated palladium sheet is immersed in the reaction solution and the platinum precursor-containing solution is injected into the reaction solution from the solution injection member, thus coating the copper-coated palladium sheet with platinum.
