So fuel-cells

  1. 1. Solid Oxide Fuel Cells
  2. 2. IntroductionSolid Oxide Fuel Cells What Are Solid Oxide Fuel Cells ? 2nd most developed fuel cell technology Application towards power for utilities What are Solid Oxide Fuel Cells made of?
  3. 3. Solid Oxide Fuel Cells Ceramic Plates Packed in multilayerdisks One cell consists of…. …Anode …Cathode …Electrolyte Two types… Anode/ElectrolyteSupported
  4. 4. Fuel Type are Hydro Carbons (Ex Methane gas)Operates at very high Temp. from 800 to over 1000 (oC)Hydro Carbons oxidized at anode Oxygen is reduced at cathodecreates ionic current through electrolyte.
  5. 5. Example of use in power plantExhaust is C02 and H20
  6. 6. Type Operating Temp. (Degrees Celsius)Solid Oxide 500-1000Polymer Electrolyte 50-100Molten Carbonate Alkaline 600Shows the different operating temp. of common fuel cellsEfficiency Vs Power graphHas Efficiencies as high as 70%
  7. 7. Type Operating Temp. (Degrees Celsius)Solid Oxide 500-1000Polymer Electrolyte 50-100Molten Carbonate Alkaline 600Shows the different operating temp. of common fuel cellsEfficiency Vs Power graphHas Efficiencies as high as 70%
