The relationship between the Weibull modulus of bending strength and its thickness of single cell before and after reduction was investigated by a coaxial ring force method. The Weibull modulus of NiO-YSZ anode supported cell is 4.56, 4.78 and 6.16 for the thickness of 1.1 mm, 0.9 mm and 0.7 mm, respectively. The Weibull modulus increases gradually with the decrease of sample thickness due to the reduced internal defect number of anode. The Weibull modulus of Ni-YSZ anode supported cell increases to 8.66, 12.49 and 9.37, respectively, since a plastic Ni phase inhibits the crack propagation. The single cell with a thickness of 0.9 mm shows a greater performance with the corresponding bending strength of 122.9 MPa. The crack sources of the sample mainly come from the internal defects of the anode and the agglomeration of Ni particles. Based on the experimental results, the influence of single cell thickness on its mechanical properties can be demonstrated at different crack source types and fracture modes.
