Comparing the Efficiency of Fuel Cells to Other Power Sources

This chapter explores the efficiency of fuel cells in generating electricity and compares it to gasoline-powered automobiles and electric batteries. It highlights that while fuel cells can be up to 80% efficient, their efficiency decreases when converting electricity into mechanical power. Gasoline-powered cars have an efficiency of about 20% while electric batteries can reach 90%. The chapter concludes by hinting at future discussions on fuel cells.
