Entry requirements

120 credits with 90 credits in chemistry and physics, with at least 60 credits in chemistry. 5 credits electrochemistry. Proficiency in English equivalent to the Swedish upper secondary course English 6.

Learning outcomes

On completion of 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

Instruction

Lectures, seminars, laboratory work.

Assessment

Written examination (8 credits) at the end of the course. A pass in the laboratory course is also required and is assigned 2 credits.

If there are special reasons for doing so, an examiner may make an exception from the method of assessment indicated and allow a student to be assessed by another method. An example of special reasons might be a certificate regarding special pedagogical support from the disability coordinator of the university.
