This University of Wisconsin project will focus on advancing the fundamental understanding of how solid oxide fuel cell cathodes operate such that their performance can be improved. This project will center around the role of material interfaces in determining electrochemical performance. Advanced physical characterization tools will be employed in support of a coordinated approach consisting of ab initio modeling and a unique electrochemical characterization technique called Non-Linear Electrochemical Impedance Spectroscopy. The results will be interpreted to determine the operation mechanisms and identify new material architectures thereby enabling improved fuel cell performance.
This project focuses on advancing the fundamental understanding of how cathodes operate, centering on the role of material interfaces in determining electrochemical performance. Improved cell/stack life and performance will reduce operating cost and increase efficiency, resulting in reduction in the cost of electricity and reduction of CO2 emissions from the entire platform. Specifically, this project will determine new operation mechanisms and material architectures using advanced physical and electrochemical characterization techniques and tools.
