  • Method for creating solid oxide fuel cell anodes and electrodes for other electrochemical devices
    Patent number: 7455700
    Abstract: A method for forming an anode supported electrochemical device, such as a SOFC, is disclosed. A thin layer of electrolyte 310 is supported on an anode layer comprised of an active anode layer 320 and a bulk anode layer 340. The bulk anode layer includes silicon carbide 340 in an amount between about 0.5 and 10% by weight. A cathode layer on an opposing side of the electrolyte completes the cell. The presence of the silicon carbide 340 in the supporting anode layer 340 has been found to reduce room temperature camber due to thermal expansion coefficient mismatches.
    Type: Grant
