Energy Sources & Systems: Fuel Cells
This PowerPoint presentation, from Dr. Darwin Boyd's Sustainable Energy I course at Kent State University, introduces college students to the history, chemistry, and use of fuel cells. The slides cover the five major types of fuel cells, polymer electrolyte membrane (PEM), alkaline (AFC), phosphoric acid (PAFC), molten carbonate (MCFC), and solid oxide (SOFC), as well as the advantages and disadvantages of fuel cell technology. Many of the slides include presenter notes.
