Oxygen Catalysts for Reversible Alkaline Fuel Cells

The primary goal of this project is to develop advanced catalysts and membrane electrodes assembly (MEAs) that may help to revive reversible AMFCs in stationary energy storage. 


At UB, we make three efforts to reach this goal by developing high-performance platinum-group metal (PGM)-free catalysts for the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) in reversible AMFCs similar to discharging and charging processes in a battery. In a collaboration with industry (Giner Inc) and National Renewable National Laboratory (NREL), we further incorporate the developed catalysts with selected anion-exchange ionomer and membranes with good conductivity and stability for MEA design and fabrication. U.S. DOE Energy Efficiency and Renewable Energy Office financially supports the research.
