In solid oxide fuel cell devices critical charge and element transport as well as reactions are controlled by surfaces and interfaces. Yet these interfaces degrade during the operation affecting the lifespan of the device.
We focus on engineering surface and grain boundary crystallography of the particles in contact with pores and the grain boundaries via advanced processing. Currently systematic studies linking electrochemical performance and degradation to the surface and grain boundary crystallography are not available.
We challenge this knowledge gap to quantitatively guide material and component design and adjustment of grain boundary structure and crystallography through processing.
