MetalAir Cells

The investigations of various types of carbon-based catalysts allow suitable air electrodes to be developed for use in the large variety of metalair cells and batteries designed in this laboratory. 

In polymer electrolyte membrane (PEM) fuel cells and metalair batteries, the most challenge reaction is the catalytic ORR due to its slow kinetics when compared to that of anode fuel or metal electrooxidation. Therefore, developing ORR electrocatalysts and their associated catalyst layers (CLs) are the major efforts in overcoming both the technology and commercialization challenges. Thus, exploring new catalysts, improving catalyst activity... 

Oxygen evolution is the counter electrode reaction in several electrolytic processes (e.g. metal extraction, chromium plating, several organic electrosyntheses) while oxygen reduction is the desired cathode reactions in fuel cells and metalair batteries, a potential cathode reaction in improved chlor-alkali cells and a component reaction in corrosion.
