“…The repetitive changes of Ni volume are the main cause of this degradation process that damages the YSZ network, 133 including the electrode/electrolyte interface, and reduces TPB density because of accelerated Ni coarsening. A comprehensive quantification of redox cycling can be achieved by coupling 3D tomography, real‐time impedance spectroscopy, and mechanical analysis 94,134 . The unpredictable and high levels of degradation are probably the reason for the intensive studies of Ni redox cycling and the efforts to find a preventing strategy.…”

In this review paper, a critical assessment of the main degradation processes in three key components of solid oxide fuel cells and electrolysers (negative and positive electrodes and the interconnect) is undertaken, attempting prioritization of respective degradation effects and recommendation of the best approaches in their experimental ascertainment and numerical modeling.Besides different approaches to quantifying the degradation rate of an operating solid oxide cell (SOC), the latest advancements in microstructural representation (3D imaging and reconstruction) of SOC electrodes are reviewed, applied to the quantification of triple-phase boundary (TPB) lengths and morphology evolution over time. The intrinsic degradation processes in the negative (fuel)This is an open access article under the terms of the Creative Commons Attribution-NonCommercial License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited and is not used for commercial purposes.
