“…In addition, studies showed that different composites of high-order nickelate RP oxides with standard electrolyte materials such as YSZ and GDC used as cathode of SOFC also improved the performance of the cell. [227,228] With the acceptable TEC value (~12×10 À 6 K À 1 ) of these materials at intermediate temperature SOFC, and their structural stability at 700 °C, these materials present promising alternatives for use as cathodes in SOFC applications. Anode-supported single cells assembled with the Pr 2 NiO 4 + δ cathode have demonstrated a compatible power density of 650-700 mWcm À 2 at 0.8 V cell voltage at 750 °C, with a much lower degrading rate of only 1 %-3 % per 1000 h compared to LSCF-based cells, which have a degrading rate of 10-20 % per 1000 h, [229] see Figure 19 a-c.…”

The high‐temperature solid oxide fuel cells (SOFCs) are the most efficient and green conversion technology for electricity generation from hydrogen‐based fuel as compared to conventional thermal power plants. Many efforts have been made to reduce the high operating temperature (>800 °C) to intermediate/low operating temperature (400 °C<T<800 °C) in SOFCs in order to extend their life span, thermal compatibility, cost‐effectiveness, and ease of fabrication. However, the major challenges in developing cathode materials for low/intermediate temperature SOFCs include structural stability, catalytic activity for oxygen adsorption and reduction, and tolerance against contaminants such as chromium, boron, and sulfur. This research aims to provide an updated review of the perovskite‐based state‐of‐the‐art cathode materials LaSrMnO3 (LSM) and LaSrCOFeO3 (LSCF), as well as the recent trending Ruddlesden‐Popper phase (RP) and double perovskite‐structured materials SOFCs technology. Our review highlights various strategies such as surface modification, codoping, infiltration/impregnation, and composites with fluorite phases to address the challenges related to LSM/LSCF‐based electrode materials and improve their electrocatalytic activity. Moreover, this study also offers insight into the electrochemical performance of the double perovskite oxides and Ruddlesden‐Popper phase materials as cathodes for SOFCs.

“…The Ruddlesden–Popper (RP) phases with the general formula of (AO)(ABO 3 ) n or A n+1 B n O 3n+1 consist of the perovskite layers ABO 3−δ alternating with the rock salt layers A 2 O 2+δ [ 58 , 60 , 63 , 69 , 129 , 159 , 285 , 286 , 287 , 288 , 289 , 290 ]. The important feature of RP phases, which makes them attractive SOFC cathodes and oxygen-separation-membrane materials, is a fine oxygen transport provided via the cooperative mechanism of oxygen migration.…”

“…The important feature of RP phases, which makes them attractive SOFC cathodes and oxygen-separation-membrane materials, is a fine oxygen transport provided via the cooperative mechanism of oxygen migration. In this case, both lattice and interstitial oxide anions accumulating at a high level are involved in the process of oxygen transport ( Figure 20 ) [ 55 , 58 , 60 , 63 , 69 , 159 , 285 , 288 , 291 , 292 , 293 , 294 , 295 , 296 , 297 ]. This allows them to reach superior oxygen mobility compared to other MIECs ( Figure 21 ).…”

Oxygen and hydrogen mobility are among the important characteristics for the operation of solid oxide fuel cells, permselective membranes and many other electrochemical devices. This, along with other characteristics, enables a high-power density in solid oxide fuel cells due to reducing the electrolyte resistance and enabling the electrode processes to not be limited by the electrode-electrolyte-gas phase triple-phase boundary, as well as providing high oxygen or hydrogen permeation fluxes for membranes due to a high ambipolar conductivity. This work focuses on the oxygen and hydrogen diffusion of mixed ionic (oxide ionic or/and protonic)–electronic conducting materials for these devices, and its role in their performance. The main laws of bulk diffusion and surface exchange are highlighted. Isotope exchange techniques allow us to study these processes in detail. Ionic transport properties of conventional and state-of-the-art materials including perovskites, Ruddlesden–Popper phases, fluorites, pyrochlores, composites, etc., are reviewed.

“…In addition to a high electronic conductivity, these materials exhibit both high oxygen diffusivity and surface exchange coefficient (D and k, respectively) at the operating temperatures. Two different kind of efficient candidates are generally considered: (i) the oxygen deficient perovskites such as La 0.6 Sr 0.4 CoO 3-δ (LSC) and La 0.6 Sr 0.4 Fe 0.8 Co 0.2 O 3-δ (LSFC) [7][8][9][10][11], which are nowadays the standard SOEC materials and (ii) the oxygen over-stoichiometric oxides, such as the lanthanide nickelates Ln 2 NiO 4+δ (Ln = La, Pr, Nd), which belong to the so-called Ruddlesden-Popper series Ln n+1 Ni n O 3n+1 (here with n = 1) [12]. These compounds show a K 2 NiF 4 -type layered structure, with alternating LnNiO 3 perovskite layers and LnO rocksalt layers within which reside the additional interstitial oxygen atoms.…”

Mixed ionic electronic conductors (MIECs) oxides are used as electrode materials for solid oxide cell (SOC) application, as they combine high electronic conductivity as well as high oxygen diffusivity and oxygen surface exchange coefficients. The ionic transport properties can be directly determined thanks to the isotopic exchange depth profiling (IEDP) method. To date, the reported measurements have been performed at ambient pressure and below. However, for a higher efficiency of hydrogen production at the system level, it is envisaged to operate the cell between 10 and 60 bar. To characterize the MIEC oxides properties in such conditions, an innovative setup able to operate up to a total pressure of 50 bar and 900°C has been developed. The main goal of this study was to compare the behavior of two types of reference materials: the oxygen deficient La‐Sr‐Fe‐Co perovskites, and the overstoichiometric lanthanide nickelates Ln2NiO4+δ (Ln = La, Pr, Nd). Diffusion and surface exchange coefficients obtained under 6.3 bar of oxygen are measured and their evolution discussed in light of the change in oxygen stoichiometries. This analysis allows better understanding of the dependency of the surface exchange coefficient with the oxygen partial pressure.
