“…This is owing to the bare substrate in the uncoated sample, which oxidizes freely. Afterward, as the oxidation time continues to increase, the oxidation rate reduces on account of the formation of Cr 2 O 3 . After isothermal oxidation, the weight gain values of uncoated and AS22-air samples are 1.613 and 0.498 mg/cm 2 , respectively, while the AS22-Ar sample possesses a weight gain of merely 0.415 mg/cm 2 .…”

Chromium (Cr) evaporation of ferritic stainless steel (FSS) interconnects is considered to be the main reason for severe deterioration of solid oxide fuel cells (SOFCs). To suppress the influence of Cr evaporation, the development of a protective coating material on the FSS interconnects has been proved to be an effective way. Herein, we prepare a Co-containing protective coating via a facile pack cementation technique in different atmospheres on an AISI 430 FSS interconnect. The obtained coating is valid for enhancing the oxidation resistance and electrical performance of the FSS interconnect. After the isothermal oxidation test, the weight gain of the coated sample in Ar (0.415 mg/cm2) is smaller than that of uncoated (1.613 mg/cm2) and coated samples in air (0.498 mg/cm2). In addition, after the area specific resistance (ASR) test, the coated sample (73.68 mΩ cm2) in Ar has the lowest ASR compared with the uncoated (236.88 mΩ cm2) and coated samples in air (96.32 mΩ cm2). These results indicate that the formation of the CoFe2O4 spinel layer heightens oxidation resistance and electrical properties through preventing the outward diffusion of Cr3+ and inward diffusion of O2–. This work verifies that the Co-containing protective coating prepared in Ar is a promising coating material for SOFC applications.

“…LNCO uses BaZr 0.1 Ce 0.7 Y 0.2 O 3 as an electrolyte material in a proton-conducting electrolyte-based fuel cell, and when hydrogen is used as a fuel, it reaches a peak power density of 410 mW$cm À2 at 650 C (Su, 2016). LSN(La 1.2 Sr 0.8 NiO 4 )-cell and PSN(Pr 1.2 Sr 0.8 NiO 4 )-cell achieve the expected high electrochemical performance and good reversibility (Yang et al, 2018a) Generally, spinel oxide is used as a coating for the interconnecting material to reduce the contact resistance between the electrode and the interconnecting and improve the stability of the material (Hassan et al, 2020;Hu et al, 2020;Lei et al, 2021;Minghai and Panpan, 2020;Mosavi and Ebrahimifar, 2020;Talic et al, 2017). Considering the high electronic conductivity of spinel, the researchers evaluated it as an SOFC cathode material.…”

Reversible solid oxide fuel cell (RSOFC) is an energy device that flexibly interchanges between electrical and chemical energy according to people's life and production needs. The development of cell materials affects the stability and cost of the cell, but also restricts its market-oriented development. After decades of research by scientists, a lot of achievements and progress have been made on RSOFC materials. According to the composition and requirements of each component of RSOFC, this article summarizes the research progress based on materials and discusses the merits and demerits of current cell materials in electrochemical performance. According to the efficiency of different materials in solid oxide fuel cell (SOFC mode) and solid oxide electrolyzer (SOEC mode), the challenges encountered by RSOFC in the operation are evaluated, and the future development of RSOFC materials is boldly prospected.

“…A number of ways to reduce the impact of the aforementioned phenomena have been proposed. One of them is the surface modification of metallic interconnects, which involves the deposition of a protective-conducting layer by means of various methods, including screen-printing [24][25][26][27][28], dip-coating [29], electroplating [30][31][32][33][34], RF-sputtering [35], cost-effective atmospheric plasma spray (APS) [36,37] and large area filtered arc deposition (LAFAD) [38]. The materials that seem most suitable for such modifications based on current research are spinels with the following compositions: (Mn,Co) 2 O 3 [39][40][41][42][43][44][45][46], (Cu,Mn) 2 O 4 [47][48][49], (Co,Mn,Me) 2 O 3 (where Me: Cu, Ni, Fe, Ag, Ce, Y) [50][51][52][53][54][55][56][57].…”

The Crofer 22 H ferritic steel substrate was coated with an Mn1.45Co1.45Cu0.1O4 spinel by means of electrophoresis. After high-temperature oxidation under thermal cycling conditions, the physicochemical properties of the obtained system were evaluated. During 48-h cycles that involved heating the samples up to temperatures of either 750 or 800 °C, the oxidation kinetics of both coated and unmodified steel approximately obeyed the parabolic rate law. The unmodified steel was oxidized at a higher rate than the system consisting of the substrate and the coating. In its bulk form, the spinel consisted entirely of the cubic phase and it exhibited high electrical conductivity. The Mn1.45Co1.45Cu0.1O4 coating, on the other hand, was compact and consisted of two phases—the cubic and the tetragonal one—and it was characterized by good adhesion to the metallic substrate. After cyclic oxidation studies conducted for the two investigated temperatures (750 or 800 °C), the coating was determined to provide a considerable improvement in the electrical properties of the Crofer 22 H ferritic steel, as demonstrated by the area-specific resistance values measured for the steel/coating system. The evaporation rate of chromium measured for these samples likewise indicates that the coating is capable of acting as an effective barrier against the formation of volatile compounds of chromium. The Mn1.45Co1.45Cu0.1O4 spinel can therefore be considered a suitable material for a coating on the Crofer 22 H ferritic steel, with intermediate-temperature solid oxide electrolyzer cells as the target application.
