Abstract
In this work, a quantitative correlation between the adhesion strength and the ohmic resistance at the interfaces between the electrolyte and the cathode was established. A cell consisting of LSM/YSZ/LSM was used to tune the interface adhesion strength by changing the sintering temperature. Electrochemical impedance spectroscopy was used to measure the interfacial resistance. The interfacial adhesion strength was obtained by using a mechanical tensile test. The result shows that the ohmic area specific resistance decreases gradually with the increase of the adhesion strength at the interfaces and reaches a plateau at a certain value. It seems that the polarization resistance has the similar changing trends with that of the ohmic resistance.
