This course discusses fundamentals and applications of electrochemical systems from an engineering perspective. Aspects of thermodynamics, reaction kinetics, and transport phenomena relevant to the description of electrode/electrolyte interfaces and charge transfer reactions are covered. Topics include cell equilibrium (Nernst equation), reactions rates within Butler-Volmer and Marcus theory, electrochemical double layer structure, ion transport (Poisson-Nernst-Planck equation), potential and current distributions in electrochemical cells, and experimental electroanalytical techniques. Applications include fuel cells, electrolyzers, batteries, sensors, and corrosion. Contact instructor to request to take prerequisites as corequisites. Same as CHEN 4490.
