Metal-air battery, fuel cell, air electrode
Lithium-based batteries, portable electronic devices
Current power outputs and activated life of metal-air system are limited by high polarization of air electrode and poor water management.
This research proposes to develop a novel air electrode active layer - noble metal (Pt, Pd, Ru) decorated carbon matte – to decrease the polarization of oxygen reduction, and to design and incorporate a micropump to the air electrode to significantly improve water management and mechanically enhance oxygen flow during electrochemical reaction.
