Lecture 40: Fuel Cells – Basic types and design

 

  • It consists of three components - a cathode, an anode, and an electrolyte sandwiched between the two.
  • Oxygen from the air flows through the cathode
  • A fuel gas containing hydrogen, such as methane, flows past the anode.
  • Negatively charged oxygen ions migrate through the electrolyte membrane react with the hydrogen to form water,
  • The reacts with the methane fuel to form hydrogen (H2) & carbon dioxide (CO2).
