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.
