Fundamental Investigators and Rational Design of Durable, High-Performance Cathode Materials

Performer: Georgia Tech Research Corporation

Project No: FE0009652

Project Description

The Georgia Institute of Technology (Georgia Tech) will use specially-designed electrodes and cells, such as electrodes of thin films and patterned electrodes, to study the electrochemical response of lanthanum strontium cobalt ferrite (LSCF) cathodes under realistic operating conditions (ROC), to probe and map contaminants on the LSCF, and to characterize the correlation between electrochemical performance and microstructure/morphology of LSCF cathodes as well as their evolution over time. A range of characterization tools will be used to study the chemical and structural changes during fuel cell operation. Electrochemical techniques, such as impedance and DC polarization, will be intensively applied to characterize the cathode performance, which will be correlated with the structural and compositional evolution of the LSCF cathode under ROC. Proper characterization, modeling techniques, and prediction tools will be used to help in formulating an effective strategy to mitigate the stability issues and predict new catalyst materials that can enhance the stability of LSCF. Finally, the performance and stability of the modified LSCF cathode will be validated in commercially available cells under ROC.
