1. Solid Oxide Fuel Cells By Raymond Adorno MEEN 3344 Material Science Taught by Dr. Peel

2. Introduction Solid 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. Solid Oxide Fuel Cells Ceramic Plates Packed in multilayer disks One cell consists of…. …Anode …Cathode …Electrolyte Two types… Anode/Electrolyte Supported

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 cathode creates ionic current through electrolyte.

5. Example of use in power plant Exhaust is C02 and H20

6. Type Operating Temp. (Degrees Celsius) Solid Oxide500-1000 Polymer Electrolyte 50-100 Molten Carbonate Alkaline 600 Shows the different operating temp. of common fuel cells Efficiency Vs Power graph Has Efficiencies as high as 70%
