After completing the course the student should be able to:
apply the Nernst, Butler-Volmer and Tafel equations to electrochemical systems and describe the difference between equilibrium properties and properties of electrochemical systems in which currents are present
describe and apply electrochemical methods such as: chronoamperometry, cyclic voltammetry, chronopotentiometry and coulometry, as well as the type of information that can be obtained with these techniques
describe how ac impedance, spectroelectrochemistry and the use of coupled techniques to electrochemistry can be used to obtain information about electrochemical systems and the structure of energy relevant materials
explain the concepts of and common techniques for the study of homogeneous and heterogeneous catalytic processes
explain the advantages and disadvantages of using micro- and nanostructured materials and surface-modified electrodes in electrochemical investigations
explain the function of batteries and fuel cells as well as the commonly involved underlying electrochemical reactions
use simulation methods to study electrochemical systems
