  2. 2. BY<br /><ul><li>KATE, WISDOM DEEBEKE.
  3. 3. LOLOMARI, SONGO JANE, &
  4. 4. N-NAMDI, ADOMA BIG. </li></ul>@<br />INTO<br />NEWCASTLE UNIVERSITY.<br />THURDAY, MARCH 17, 2011<br />PRESENTED BY KATE, LOLOMARI & ADOMA.<br />2<br />
  5. 5. Presentation outlines<br /><ul><li>What is a fuel cell?
  6. 6. Types of hydrogen fuel cell
  7. 7. Components of hydrogen</li></ul> fuel cell and mechanisms of<br /> operations<br /><ul><li>Location and uses</li></ul>PRESENTED BY KATE, LOLOMARI & ADOMA.<br />3<br />
  8. 8. What is a fuel cell ?<br /><ul><li>Is an electrochemical device
  9. 9. Combines hydrogen and oxygen
  10. 10. Produce electrical energy
  11. 11. Water and heat are bye-products
  12. 12. Used in different applications
  13. 13. Is a reverse electrolysis process</li></ul>PRESENTED BY KATE, LOLOMARI & ADOMA.<br />4<br />
  14. 14. Types of hydrogen fuel cell<br /><ul><li>Classified by the type of electrolyte used
  15. 15. Operates at different temperature
  16. 16. All use hydrogen as a fuel
  17. 17. The hydrogen can be extracted from</li></ul> Natural gas<br /> biogas <br /> methanol by reformation <br /> propane<br /><ul><li>Or by the electrolysis of water</li></ul>PRESENTED BY KATE, LOLOMARI & ADOMA.<br />5<br />
  18. 18. Types of hydrogen fuel cell<br />Alkaline(AFC)<br />Polymer Electrolyte Membrane<br />(PEMFC)<br />Phosphoric Acid(PAFC)<br />Polymer Electrolyte Membrane(PEMFC)<br />Types of Fuel Cells<br />Molten Carbonate(MCFC)<br />Direct Methanol<br />(DMFC)<br />Direct Methanol(DMFC)<br />Solid Oxide<br />(SOFC)<br />Solid Oxide(SOFC)<br />PRESENTED BY KATE, LOLOMARI & ADOMA.<br />6<br />
  19. 19. Components of hydrogen fuel cell<br /><ul><li>Anode </li></ul> -Negative post of the cell<br /> -Conducts free electrons from<br /> hydrogen <br /> -Etched channel disperse H2 over<br /> catalyst surface<br /> 2H2 4H+ + 4e-<br />PRESENTED BY KATE, LOLOMARI & ADOMA.<br />7<br />
  20. 20. Components of hydrogen fuel cell<br /><ul><li>Cathode</li></ul> -positive post of the cell<br /> -conducts free electrons back from<br /> external circuit to<br /> catalyst<br /> -etched channel disperse oxygen to<br /> catalyst surface<br />O2 + 4H+ + 4e- 2H2O<br />PRESENTED BY KATE, LOLOMARI & ADOMA.<br />8<br />
  21. 21. DIAGRAM SPEAKS<br />PRESENTED BY KATE, LOLOMARI & ADOMA.<br />9<br />
  22. 22. Components of hydrogen fuel cell<br /><ul><li>Electrolyte</li></ul> -Proton Exchange<br /> Membrane(PEM)<br /> -specially treated material<br /> -only conducts positively<br /> charged ions(H ions)<br /> -membrane blocks electrons<br />PRESENTED BY KATE, LOLOMARI & ADOMA.<br />10<br />
  23. 23. Components of hydrogen fuel cell<br /><ul><li>Catalyst</li></ul> -facilitates reaction of oxygen<br /> with hydrogen<br /> -usually platinum powder<br /> coated onto carbon paper<br /> -rough and porous<br /> -the platinum catalyst side faces<br /> the PEM<br />PRESENTED BY KATE, LOLOMARI & ADOMA.<br />11<br />
  24. 24. LOCATION AND USES<br /><ul><li>USES</li></ul> To back up power<br /> -to power device that use battery<br /> -to power machineries such as truck,<br /> buses, vehicles and ships<br /><ul><li>Advantages over other fuel sources</li></ul> -excess heat released is used for other<br /> applications<br /> -operates quickly with fewer moving parts<br /> -environmental friendly, no pollution<br /> -high efficiency than others<br />PRESENTED BY KATE, LOLOMARI & ADOMA.<br />12<br />
  25. 25. LOCATION AND USES<br /><ul><li>LOCATIONS</li></ul> -Reykjavik fuel station in<br /> Iceland<br /> -California hydrogen<br /> highway, USA.<br /> -South Carolina station, USA<br /> -Japan hydrogen highway<br />PRESENTED BY KATE, LOLOMARI & ADOMA.<br />13<br />
