“…To introduce TiO 2 -supported Ni particles onto the stem of NiO-Fe 2 O 3 scaffold (~40% porosity 30 ), an aqueous solution containing Ti and Ni ions at the stoichiometric concentration of NiTiO 3 (NTO) was prepared as follow. Tetrabutyl titanate (C 16 H 36 O 4 Ti, Sinopharm) was dissolved in a dilute nitric acid aqueous solution under stirring, and then stoichiometric amount of Ni nitrate (Ni(NO 3 ) 2 ·6H 2 O, Sinopharm) was added prior to the addition of citric acid (CA) and ethylenediamine tetraacetic acid (EDTA) as the chelants.…”

Ni0.9Fe0.1 alloy-supported solid oxide fuel cells with NiTiO3 (NTO) infiltrated into the cell support from 0 to 4 wt.% are prepared and investigated for CH4 steam reforming activity and electrochemical performance. The infiltrated NiTiO3 is reduced to TiO2-supported Ni particles in H2 at 650 °C. The reforming activity of the Ni0.9Fe0.1-support is increased by the presence of the TiO2-supported Ni particles; 3 wt.% is the optimal value of the added NTO, corresponding to the highest reforming activity, resistance to carbon deposition and electrochemical performance of the cell. Fueled wet CH4 at 100 mL min−1, the cell with 3 wt.% of NTO demonstrates a peak power density of 1.20 W cm−2 and a high limiting current density of 2.83 A cm−2 at 650 °C. It performs steadily for 96 h at 0.4 A cm−2 without the presence of deposited carbon in the Ni0.9Fe0.1-support and functional anode. Five polarization processes are identified by deconvoluting and data-fitting the electrochemical impedance spectra of the cells under the testing conditions; and the addition of TiO2-supported Ni particles into the Ni0.9Fe0.1-support reduces the polarization resistance of the processes ascribed to CH4 steam reforming and gas diffusion in the Ni0.9Fe0.1-support and functional anode.

“…The power densities of our cells were compared to those of the reported cermet-and metal-supported SOFCs, as shown in Figure 4d and Table S1 (Supporting Information). As compared with Ni-YSZ cermet-supported cells, [41] metal-supported cells [35,[42][43][44][45][46][47] exhibit significantly higher electrochemical performance, which results from the inherent high conductivity of metals and lowering the thickness of the cell components. Among them, our nanocomposite cell exhibited superior MPDs compared to the previously reported metal-supported cells [10,43,[48][49][50][51][52][53] and nanocomposites.…”

“…Metal-supported structures play a crucial role in ensuring the structural stability of RSOCs owing to their notable thermal and mechanical properties, including high ductility, thermal shock resistance, and inertness under reducing conditions at high temperatures. [7,8] Furthermore, replacing conventional ceramics with metal supports, such as stainless steel, [9] nickel (Ni), [10] Ni-iron (Fe), and NiCrAlY, [11] enhances cell performance by improving the current collection with excellent electrical conductivity. Among the reported metal supports, Ni-Fe alloy DOI: 10.1002/admt.202300465 supports have garnered significant attention for their remarkable chemical stability and economic viability.…”

Solid oxide cells are reversible energy‐conversion devices for electric power generation and fuel production with high efficiency. However, robust cell structures and multifunctional electrodes must be provided to achieve high cell performance under multifuel conditions. Herein, a precisely controlled metal‐supported structure and dual‐nanocomposite catalyst is presented. The thermal and shrinkage behaviors of the metal supports play a crucial role in determining the interconnectivity between cell components. Compared to micron‐sized cermets, the dual‐nanocomposite electrode with tremendous three‐phase boundaries drastically improves cell performance by increasing the electrochemical activity for diverse fuel reactions. The developed cells exhibited outstanding maximum power densities of 1.1 and 1.0 W cm−2 in fuel‐cell mode using H2 and CO fuels, and current densities of −0.61 and −0.5 A cm−2 in electrolysis‐cell mode (1.3 V) under H2O/H2 and CO2/CO conditions at 650 °C. These findings suggest fundamental techniques for improving the structural stability and activity of cell components to operate in diverse fuel systems.

Metal‐supported solid oxide fuel cells (MSCs) offer certain strategic advantages over the more conventional solid oxide fuel cells (SOFCs), which comprise only ceramic materials. Since alloys such as ferritic steels are very similar in their coefficient of thermal expansion (CTE) with ceramic components, viz., cerias, zirconias, and nickel oxide doped with either of them, they could provide excellent thermal cyclability while maintaining a strong interlayer bond. Therefore, in an anode‐supported cell the entire NiO‐ceramic support can be replaced by a ferritic steel porous support—the catalytically active NiO is therefore, a functional layer only. A huge savings in materials cost is achievable, because cerias and zirconias [usually doped with Y, Gd, Sm rare earth (RE) elements] are considerably more expensive that ferritic steels. Lowering the capital costs for SOFCs is an extensive global undertaking with US Department of Energy (DOE) laying down targets such as ~$ 200/kW for the stack itself, in order for SOFCs to become competitive with grid power costs and to offer a power source that promises 24 × 7 power supply for critical applications. This will eventually lead to a premier electricity generation device in the distributed power space, with the highest known electrical efficiencies (>50%). MSCs need very robust, high precision, and cost‐effective manufacturing techniques, which are scalable to high volumes. One of the main goals in this review is to showcase some of the work done in this area since the last review (2010), and to assess the technology challenges, and new solutions that have emerged over the past few years.
