Conversion in fuel cells:
Learn and understand the basic design and operating principles and constraints in direct conversion of chemical energy into electricity by fuel cells, characterized by high efficiency at small power size. Fuel cells are devices at the crossroads between the disciplines of mechanical, chemical, electrical and materials science engineering, and thus an excellent study case to illustrate the importance of interdisciplinary research and knowledge.
