COURSE OBJECTIVE:
Introduce students to the science and technology behind the direct conversion of chemical energy into electricity generated in fuel cells, electrochemical motors. Because of the potential to reduce negative impacts on the environment as well as the geopolitical consequences of the use of fossil fuels, fuel cells could replace internal combustion engines in a hydrogen based economy.

2. Historical development of the fuel cells the structure of fuel cells, auxiliary systems.
3. Types of fuel cells according to electrolyte, operating temperature and fuel used: proton conducting polymer fuel cell membrane PEMFC, phosphoric acid fuel cell PAFC, methanol fuel cell DMFC, alkaline fuel cell AFC, molten carbonate fuel cell MCFC, solid fuel cell SOFC.
4. Advantages and disadvantages (development challenges) of fuel cells.
5. Fuel production and properties for fuel cells
6. Thermodynamics and polarization of fuel cells
7. Calculation problems I (Ohms law, Faraday's laws, Enthalpy of reaction)
8. Calculation problems I II (Entropy, Gibbs energy, Polarizations)
9. Characterization of fuel cells I (Electrochemical impedance spectroscopy, Cyclic voltammetry)
10. Characterization of fuel cells II (Mechanical tests, Scanning electron microscopy, X ray diffraction, Nuclear magnetic resonance, Infrared spectroscopy)
11. Proton conducting polymer membrane fuel cell PEMFC
12. Fuel cell with solid phase oxide (ceramic) SOFC.
13. Selected topics from fuel cells student presentations, seminar assignments
14. Final exam
