The lecture covers the properties of gases, the first, second and third law of thermodynamics, physical transformations of pure substances, simple mixtures, chemical equilibrium and kinetics.
In this course, we will discuss the physical-chemical properties of materials, the kinetic properties of catalysts, and the design of electrochemical devices for the conversion and storage of energy. The first part of the course will focus on a variety of fuel cells (proton exchange membrane fuel cells, direct methanol fuel cells, phosphoric acid fuel cells, alkaline fuel cells, direct methanol fuel cells), examining the current performance limitations and the different materials degradation/aging processes. Subsequently, we will discuss the materials and processes for water electrolysis and for chlor-alkaline electrolyzers (membrane cells, depolarizing cathodes, etc.) as well as the possiblity for the electrochemical reduction of CO2 to synthesis gas and fuels. In the last part of the course we will discuss redox-flow batteries and lithium-ion batteries.
The course Electrochemistry for Energy Materials is a joined lecture of the chairs of Technical Electrochemistry (Prof. Gasteiger) and Synthesis and Characterization of Innovative Materials (Prof. Nilges). It comprises of both weekly lecture (90 min) and tutorial (60 min) and is graded after a written examination (90 min) at the end of the semester.
- electrochemical cells, thermodynamics, reference electrodes
- ionic conduction in electrolytes / activity coefficients
- electrochemical kinetics
- mass transport / diffusion effects
- cyclic voltammetry / rotating disk electrodes / micro-electrodes
- AC impedance
- thermoelectrics and solid electrolytes
The practical course in physical chemistry for students in Chemistry and Chemical Engineering, Food Chemistry, Biochemistry and Teachership consists of experiments in the areas of kinetics and thermodynamics. The students learn to summarize the experimental results in writing, to calculate the experimental error and to discuss the data by comparison with the literature.
