GOALI : “Collaborative Research: An Experimental and Theoretical Study of the Microstructural and Electrochemical Stability of Solid Oxide Cells”

Project: Research project

Project Details

Description

The proposed project focuses on the microstructural and chemical changes that occur in solid oxide cells during electrolysis operation. These changes give rise to degradation of the cell performance characteristics and in some cases cell failure. It has been hypthesized that the changes occur as a result of electrochemically-induced extreme oxygen pressures, but this not well understood or verified. An understanding of these phenomena is important to determine methods to mitigate damage and reduce degradation rates to acceptable levels; this will help enable the use of solid oxide electrolysis as an important method for renewable energy storage. A main analysis tool to be utilized is three-dimensional (3D) tomography that will be used both ex situ and in a unique pseudo in situ measurement to determine microstructural evolution. This study will build on prior NSF funded projects including DMR-1506925-002 where 3D tomography methods for studying degradation have been developed.
