AI Technical Summary

Technical Problem

Conventional electroplating methods for manufacturing catalytic electrodes are costly and time-consuming, especially when using precious metals, due to the need for excessive precursor use and separate recovery processes.

Method used

A method utilizing a cyclic voltammetry current to electrodeposit active metal on both metal substrates acting as electrodes, eliminating the need for separate reference and counter electrodes, thereby reducing production time and precursor waste.

Benefits of technology

The method significantly reduces production time and minimizes precursor waste, resulting in higher performance catalyst electrodes with uniform metal deposition.

Abstract

The present invention relates to a method for manufacturing a catalyst electrode using cyclic voltammetry, the method comprising the steps of: immersing first and second metal substrates each in an electrolytic solution containing an active metal precursor; and electrodepositing an active metal on both of the metal substrates by applying a cyclic voltammetry current to the first and second metal substrates.
