This West Virginia University project will focus on advancing the fundamental understanding of how solid oxide fuel cell cathodes operate such that their performance can be improved. The 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 reaction modeling and a focus on a novel cathode material combination of Lanthanum Nickelate + Lanthanum Strontium Iron Cobalt Oxide. The results will be interpreted to determine the operation mechanisms and identify new material architectures thereby enabling improved fuel cell performance.

Project Benefits

This project focuses on developing a better understanding of the fundamental mechanisms of oxygen reduction reactions through experimental investigation and modeling. 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 utilize electrical conductivity relaxation to characterize oxygen transport behavior.
