Mechanistic Enhancement of SOFC Cathode Durability

Performer: University of Maryland

Project No: FE0009084

Program Background and Project Benefits

This project focuses on investigating the effects of contaminants on cathode degradation mechanisms in order to establish cathode composition and structures and operational conditions to enhance cathode durability. 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 the mechanistic effects of H2O and Cr vapor, CO2, and particulates on cathode durability, quantify microstructural and compositional changes, and determine the surface exchange mechanisms and coefficients using in-situ isotope exchange of labeled contaminants.
