1. Solid Oxide Fuel Cells

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 Oxide 500-1000
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%
