The present work encompasses the immediate performance characterization of a first generation LSC-based SOFC single cell by means of polarization curves, electrochemical impedance spectroscopy (EIS), the distribution relaxation times (DRT) method and equivalent circuit modeling (ECM). Besides, an endurance performance characterization based on the FCTESQA testing protocols along with EIS measurements, the aforementioned ECM and computational fluid dynamics (CFD) modelling theory has enabled to generate a time-dependent model capable of predicting performance degradation of the single cell when operating under predetermined conditions.
