Degradation of solid oxide electrolysis cells: Phenomena,mechanisms, and emerging mitigation strategies——A review
Solid oxide electrolysis cell(SOEC) is a promising electrochemical device with high efficiency for energy storage and conversion.However,the degradation of SOEC is a significant barrier to commercial viability.In this review paper,the typical degradation phenomena of SOEC are summarized,with great attention into the anodes/oxygen electrodes,including the commonly used and newly developed anode materials.Meanwhile,mechanistic investigations on the electrode/electrolyte interfaces are provided to unveil how the intrinsic factor,oxygen partial pressure p_(O_2),and the electrochemical operation conditions,affect the interracial stability of SOEC.At last,this paper also presents some emerging mitigation strategies to circumvent long-term degradation,which include novel infiltration method,development of new anode materials and engineering of the microstructure.
