Measurement of oxygen chemical potential in Gd2O3-doped ceria-Y2O3-stabilized zirconia bi-layer electrolyte, anode-supported solid oxide fuel cells

Transport through mixed proton, oxygen ion and electron/hole conductors: Analysis of fuel cells and electrolyzer cells using Onsager equations

“…No differences between the two cells thus can be detected by the usual currentevoltage plots and/or electrochemical impedance spectroscopy (EIS). The differences between the two cells, however, can be observed if inert metal probes are embedded in the electrolyte which measure 4 [19]. The measured electric potentials within the electrolyte by embedded probes will be different in the two cells, that is the distribution of 4 within the electrolyte, will be different.…”

Effect of Fe2O3 on Sm-doped ceria system solid electrolyte for IT-SOFCs

“…Solid oxide fuel cells (SOFCs) are important electrochemical devices that can directly convert chemical energy into electricity at high efficiency [1][2][3][4][5]. SOFCs have a wide range of applications in stationary power generation and transport.…”

Performance of solid oxide electrolysis cell having bi-layered electrolyte during steam electrolysis and carbon dioxide electrolysis

“…Moreover, high applied voltage in SOEC system can deteriorate ionic transfer number due to electronic conduction by the reduction of ceria electrolyte from Ce 4þ to Ce 3þ [18]. While in SOFC research, the double layer electrolyte of YSZ/GDC can be expected to be an effective solution [24], it is interesting to investigate the effect of the YSZ buffer layer in SOEC operation.…”
