(104e) Electrodes for Solid Oxide Fuel Cells and Electrolyzers

SOFC and SOE are based on electrolytes that are oxygen-ion conductors. SOFC can therefore operate on a wide range of fuels, including methane and other hydrocarbons. Likewise, electrolysis of CO2 is feasible in an SOE. However, to allow stable operation with a wider range of feeds to the electrodes, new electrode materials must be developed. This talk will describe the methods being developed at Penn that allow the electrode composition and structure to be varied easily. Results for both fuel- and air-side electrodes will be discussed.
