Electrode Modification Using Catalyst Powder

Abstract

Powders of metals, oxides, and sulfides have been widely investigated as electrochemical catalysts to enhance the performance of energy devices such as fuel cells and metal-air batteries, and to establish efficient electrolysis processes. The author has been studying electrochemical catalysts with high activities and stabilities for oxygen electrochemical reactions utilized in metal-air batteries, water splitting, and electrowinning of zinc in cooperation with domestic researchers. Here, a method to modify electrodes with catalyst powders is explained in detail in addition to evaluation methods and compensations for reliable comparison.
