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
- calculate Tafel slopes and reaction orders for multiple-step electrochemical reactions in the absence of transport limitations
- 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 and exercises. 2/3 of the exercises must be approved to qualify for the exam. During the course an excursion to visit electrochemical industries may be arranged.

Compulsory assignments

  • Midt term
  • Exercises

Further on evaluation

Access to the final examination on the condition that the mid-term test has 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.
