Abstract :
Solid oxide fuel cell (SOFC) has attracted much attention as a promising source of electrical power generation because of its high efficiency in converting chemical energy to electrical power. The main structure of SOFC is a three-layered ceramic structure with the electrolyte sandwiched by anode and cathode, operating at temperature range of 800-1000°C. In this research, a novel procedure with a laser ultrasound measurement technique and an inversion algorism is developed for the nondestructive characterization of layer properties in the SOFC. Mechanical and geometrical properties of individual layer in the SOFC cell are characterized.
