Woo-Kum Lee

Research Assistant Professor

Dr. Lee's research has focused on the study of various aspects of performance characteristics in Proton Exchange Membrane Fuel Cells (PEMFC). It includes water and heat management and the understanding of the reaction mechanism of impurity (i.e., CO, CO2, SO2, NO2 and NH4 etc) poisoning on the membrane catalyst. Experiments are preformed to find optimum operating conditions and to further examine and improve simulations.
