Study of the Durability of Doped Lanthanum Manganite and Cobaltite Based Cathode Materials Under "Real World" Air Exposure Atmosphere

Performer: University of Connecticut

Project No: FE0009682

Program Background and Project Benefits

This project focuses on developing an understanding of the electrical, chemical, and physical processes responsible for cathode degradation under real world air atmosphere exposure conditions. 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 study the role of electrode polarization and exposure conditions on cell performance degradation, examine the role of electrode poisoning in the presence of Cr vapor, and use computational tools to theoretically deduce cathode degradation mechanisms due to air contaminants.
