Description

This paper is focused on nondestructive characterization of material and geometrical properties of ceramic layers in a solid oxide fuel cell (SOFC). More specifically, elastic properties and thickness for the electrolyte layer are measured using a nondestructive procedure. The procedure employs a laser ultrasound technique to generate and detect guided acoustic waves to propagate in the layer, followed by an inversion algorithm to extract properties from the acoustic signal. The results indicate that the thickness can be determined with high accuracy remotely, and the elastic moduli are also determined with good agreement with those in some rare literature obtained with a contact manor.
