CO2-tolerant perovskite cathodes for enhanced solid oxide fuel cells: advancements, challenges, and strategic perspectives

“…Conventional characterization tools for identifying carbonate species include XRD, FT-IR spectroscopy, Raman spectroscopy, transmission electron microscopy (TEM), CO 2 -TPD, and so on. [164][165][166][167][168][169][170] The XRD technique is employed to detect the phase This journal is © The Royal Society of Chemistry 2024 structure of various carbonate groups. To be exact, the diverse carbonate structures are determined using the corresponding Joint Committee on Powder Diffraction Standards (JCPDS) cards, such as BaCO 3 (JCPDS card no.…”

A critical review of key materials and issues in solid oxide cells

“…[130,131] Surface segregation is very important and pertinent to SOCs as all electrochemical reactions are associated with the surface processes and thus plays a pivotal role in the deterioration mechanism of SOC electrodes, due to the contaminant deposition and poisoning of the electrode materials. [132][133][134][135] The majority of the SOC perovskite electrodes surface segregation issues reported are correlated to A-site cation segregation. However, in addition to the high operation temperature and oxidizing environment, the polarization direction, that is, SOFC and SOEC modes, plays an important role in the segregated species.…”
