Project Description

Case Western Reserve University will team with LG Fuel Cell Systems to develop an understanding of the microstructural basis of long-term performance loss in solid oxide fuel cell (SOFC) lanthanum strontium manganite (LSM)-based cathodes and will form strategies for improving long-term performance and microstructural and chemical stability for commercial fuel cell systems. The team will carry out accelerated testing of SOFCs with LSM-based cathodes of selected compositions. After intervals of accelerated testing and control experiments using non-accelerated conditions, the cells will undergo extensive state-of-the-art microstructural and nanochemical characterization to determine the physical and chemical changes in the cells. This program of cell fabrication, accelerated testing, microstructural characterization, and comprehensive analysis will culminate in design rules for LSM-based cathodes, informed by mechanistic understanding of the relationships between microstructural changes during operation and the long-term durability of SOFCs.

Project Benefits

The intended outcome of this work is to develop design rules for LSM-based cathodes, informed by mechanistic understanding of the relationships between microstructural changes during operation and the long-term durability of SOFCs. The benefit of this is selection and design principles for durable, high-performing SOFC cathodes. This facilitates more widespread utilization of SOFC technology, with the corresponding broader benefits of more efficient, fuel-flexible, distributed electricity generation, and the potential for greater U.S. energy independence.
