  • Presentation outlines
    • What is a fuel cell?
    • Types of hydrogen fuel cell
    • Components of hydrogen
    fuel cell and mechanisms of
    operations
    • Location and uses
    PRESENTED BY KATE, LOLOMARI & ADOMA.
    3
  • What is a fuel cell ?
    • Is an electrochemical device
    • Combines hydrogen and oxygen
    • Produce electrical energy
    • Water and heat are bye-products
    • Used in different applications
    • Is a reverse electrolysis process
    PRESENTED BY KATE, LOLOMARI & ADOMA.
    4
  • Types of hydrogen fuel cell
    • Classified by the type of electrolyte used
    • Operates at different temperature
    • All use hydrogen as a fuel
    • The hydrogen can be extracted from
    Natural gas
    biogas
    methanol by reformation
    propane
    • Or by the electrolysis of water
    PRESENTED BY KATE, LOLOMARI & ADOMA.
    5
  • Types of hydrogen fuel cell
    Alkaline(AFC)
    Polymer Electrolyte Membrane
    (PEMFC)
    Phosphoric Acid(PAFC)
    Polymer Electrolyte Membrane(PEMFC)
    Types of Fuel Cells
    Molten Carbonate(MCFC)
    Direct Methanol
    (DMFC)
    Direct Methanol(DMFC)
    Solid Oxide
    (SOFC)
    Solid Oxide(SOFC)
    PRESENTED BY KATE, LOLOMARI & ADOMA.

  • Components of hydrogen fuel cell
    • Anode
    -Negative post of the cell
    -Conducts free electrons from
    hydrogen
    -Etched channel disperse H2 over
    catalyst surface
    2H2 4H+ + 4e-
    PRESENTED BY KATE, LOLOMARI & ADOMA.
    7
  • Components of hydrogen fuel cell
    • Cathode
    -positive post of the cell
    -conducts free electrons back from
    external circuit to
    catalyst
    -etched channel disperse oxygen to
    catalyst surface
    O2 + 4H+ + 4e- 2H2O
    PRESENTED BY KATE, LOLOMARI & ADOMA.
    8
  • DIAGRAM SPEAKS
    PRESENTED BY KATE, LOLOMARI & ADOMA.
    9
  • Components of hydrogen fuel cell
    • Electrolyte
    -Proton Exchange
    Membrane(PEM)
    -specially treated material
    -only conducts positively
    charged ions(H ions)
    -membrane blocks electrons
    PRESENTED BY KATE, LOLOMARI & ADOMA.
    10
  • Components of hydrogen fuel cell
    • Catalyst
    -facilitates reaction of oxygen
    with hydrogen
    -usually platinum powder
    coated onto carbon paper
    -rough and porous
    -the platinum catalyst side faces
    the PEM
    PRESENTED BY KATE, LOLOMARI & ADOMA.
    11
  • LOCATION AND USES
    • USES
    To back up power
    -to power device that use battery
    -to power machineries such as truck,
    buses, vehicles and ships
    • Advantages over other fuel sources
    -excess heat released is used for other
    applications
    -operates quickly with fewer moving parts
    -environmental friendly, no pollution
    -high efficiency than others
    PRESENTED BY KATE, LOLOMARI & ADOMA.
    12
  • LOCATION AND USES
    • LOCATIONS
    -Reykjavik fuel station in
    Iceland
    -California hydrogen
    highway, USA.
    -South Carolina station, USA
    -Japan hydrogen highway
