Mechanistic Enhancement of SOFC Cathode Durability
Performer: University of Maryland
Project No: FE0009084
The University of Maryland (UMD) project is a multi-faceted fundamental investigation of the effects of contaminants on cathode degradation mechanisms in order to establish cathode composition/structures and operational conditions to enhance cathode durability. The results will be used to develop hypotheses that explain the microstructural and compositional cathode performance degradation mechanisms and mitigation strategies. Phenomenological models will be developed concurrently to describe the role of architectural and operational variables on cathode performance and stability. These will result in the formation of design criteria that will be validated experimentally in terms of electrochemical performance stability in the targeted contaminant containing air in long-term tests.
