Description

Advanced monolithic solid oxide fuel cells are being assembled from thin (∼50 μm) tape-cast ceramic layers with highly tailored mechanical properties. The layers need to be free of cracks and nonbonds. A high-resolution computed tomography system with a Ir-192 source was investigated as a tool for detecting cracks and nonbonds. Results suggest that channel sizes, including internal channels, can be determined but small in-plane cracks cannot be detected
