Learning outcome

Upon course completion the student is able to - define central parts of electrochemical cells and electrochemical equipment such as anode, cathode, membrane, diaphragm, liquid junction, reference electrode, and potentiostat - define and relate mathematically basic physical and thermodynamic concepts related to electrochemical cells such as electric potential, electric field, cell potential, null potential, electrochemical potential, and activity - account for sign conventions - account for the electrochemical series and representation of electrochemical thermodynamics in Pourbaix diagrams - define and describe mathematically diffusion, migration, and convection -define transport, kinetic and ohmic overpotential -calculate the combined transport and kinetic overpotential for electrodes at which a one-electron reaction takes place and for which transport can be described through mass transfer coefficients - calculate ohmic overpotential for dilute solutions for macro- and microelectrodes such as trough electrodes, hemispherical electrodes, and disk electrodes - graphical representation of current-voltage relations for electrode reactions - calculate liquid-junction and membrane potentials in simple cases - analyze a given electrochemical cell or experiment, judge to which extent the approximations underlying the above equations apply, and explain and predict quantitatively the outcome for cases in which they do - describe the structure of the electrified interface, and define and describe mathematically the capacitance of the Helmholz layer - give an overview of applications of electrochemistry in synthesis and purification of materials and chemicals, energy storage, biology, and analysis and remediation of the environment, and provide a description of selected processes within these areas

Learning methods and activities

Lectures, exercises and term tests. The term tests and 2/3 of the exercises must be approved to qualify for the exam. The problem sets include training in use of digital tools for simulation of electrochemical processes as well as application of the theory on problems related to the UN sustainability goals. During the course an excursion to visit electrochemical industries may be arranged. The total workload is 200 hours.

Compulsory assignments

  • Midt term
  • Exercises

Further on evaluation

Access to the final examination on the condition that the term tests have been passed and that 2/3 of the problem sets have been approved. If there is a re-sit examination, the examination form may be changed from written to oral.

Specific conditions

Compulsory activities from previous semester may be approved by the department.
