Course objectives:
|
During the course of Electrochemistry, the students will familiarize themselves with the basics of electrochemistry, particularly concerning the electrochemical power sources including fuel cells. They will learn the basic functions of various sources using formulas, equations and technical details. Also, they will meet utilization of electrochemistry as a measurement and analytic method as well as theoretical background of all studied technologies. The students will experience the technology of fuel cells first hand in practical laboratory exercises, where they will gauge the power and operational parameters of fuel cells. Simultaneously, they will be using other modern measurement techniques such as digital pH indicator, digital scales, thermostatic bath, thermo camera and computer-controlled stations.
|
Requirements on student
|
Active presence during theoretical and practical exercises (1 justified absence), successful pass in the final test (at least 60%) or completion of special project assignment with emphasis on the field of study of each student and the level of expertise of each project.
