“…To achieve adequate electronic conductivity, large volumes of nickel (>30 vol% and typically 50 vol%) are needed. For the formation of an anode-supported half-cell comprising a thick supporting anode layer (typical NiO content 55–60 wt%, 300–700 µm in thickness), a functional anode layer (NiO content 45–50 wt%, 10–30 µm in thickness) and an electrolyte layer (10–30 µm), such methods as tape casting and tape calendering are used [ 81 , 82 ]. EPD was successfully applied to the formation of the anode layer on the electrolyte substrate [ 83 , 84 , 85 ], allowing comprehensive control over the layer thicknesses.…”

Electrolytic deposition (ELD) and electrophoretic deposition (EPD) are relevant methods for creating functional layers of solid oxide fuel cells (SOFCs). This review discusses challenges, new findings and prospects for the implementation of these methods, with the main emphasis placed on the use of the ELD method. Topical issues concerning the formation of highly active SOFC electrodes using ELD, namely, the electrochemical introduction of metal cations into a porous electrode backbone, the formation of composite electrodes, and the electrochemical synthesis of perovskite-like electrode materials are considered. The review presents examples of the ELD formation of the composite electrodes based on porous platinum and silver, which retain high catalytic activity when used in the low-temperature range (400–650 °C). The features of the ELD/EPD co-deposition in the creation of nanostructured electrode layers comprising metal cations, ceramic nanoparticles, and carbon nanotubes, and the use of EPD to create oriented structures are also discussed. A separate subsection is devoted to the electrodeposition of CeO2-based film structures for barrier, protective and catalytic layers using cathodic and anodic ELD, as well as to the main research directions associated with the deposition of the SOFC electrolyte layers using the EPD method.

“…Russian research group reported on fabrication process and testing of the planar large-area (100 × 100 mm 2 ) anode-supported cells with an oxide-ion conducting electrolyte based on zirconia and a bilayer Nickel-cermet supporting anode, using both the powder technologies (tape-casting and screen-printing) and physical vapor deposition (PVD) methods (magnetron sputtering and ion-beam treatment) [99]. Anode substrates consisting of (Sc2O3)0.1-(Y2O3)0.01-(ZrO2)0.89 (10Sc1YSZ) and NiO were fabricated by tape casting.…”

“…Combination of the powder and PVD techniques for fabrication of the planar anode-supported SOFCs was also used by Kang et al [100]. The supporting NiO-YSZ electrode (weight ratio of NiO to YSZ of 63:37) consisted of two layers -a highly porous anode collector layer (ACL) and a denser thin anode functional layer (AFL) -as well as in the cell described in [99]. The ACL was made by tape casting using carbon black and graphite as pore formers (10 wt%).…”

“…Significant technological advances have been achieved in the field of the planar anode-supported SOFCs. The use of ceramic powder-based technologies and vacuum methods for deposition of the functional layers, the appropriate choice of materials and the cell design resulted in excellent electrochemical characteristics of the oxide-conducting anode-supported SOFC [99]. The proton-conducting SOFC with a supporting anode, fabricated by the technologically simple and cost-effective ceramic powder-based methods, demonstrated very good power generation performance, in spite of the rather thick membrane layer (35 m) [96].…”

Solid oxide fuel cells (SOFCs) are electrochemical systems converting the energy released during fuel oxidation into electrical energy. SOFCs are considered as a promising clean energy technology due to the high efficiency of fuel-to-power conversion and environmental friendliness. The potential applications of SOFCs extend from stationary power generation units for industrial and household facilities to auxiliary power units in vehicles and portable power sources. One of the main elements of SOFCs is a solid oxide electrolyte possessing ionic conductivity at high temperatures (above 700 °C). The main challenge in the SOFC commercialization is related to their high operating temperature, which entails materials degradation, short life-time, long start-up and shut-down times, and high cost. One of the most effective ways to reduce the SOFC operating temperature is to minimize the electrolyte thickness. In this regard, fabrication of SOFCs with a thin film electrolyte has been attracting high research activity over the past few decades. Different fabrication techniques were reported to be applicable for manufacturing thin film SOFCs, and the fuel cell performance was found to be highly dependent on the appropriate selection of materials and processing technologies. The present review is focused on state-of-the-art fabrication technologies of the thin film SOFCs. A brief survey of configurations and geometries of the thin film SOFCs and methods of deposition of solid-oxide films is given. Special attention is focused on the electrical generation performance of the thin film SOFCs.

“…The problems that appear in the process of the electrode-supported cells’ formation include delamination at the electrode–electrolyte interfaces and microstructure degradation of the electrode support during electrolyte film sintering, causing difficulties in gas transportation within the thick electrode layer. To reduce these drawbacks, structural optimizations have been proposed for both anode [ 12 , 13 , 14 , 15 ] and cathode supports [ 16 , 17 ].…”

In this work, a technology was developed for the formation of BaCe0.8Sm0.2O3+1 wt% CuO (BCS-CuO)/Ce0.8Sm0.2O1.9 (SDC) thin-film electrolyte membranes for intermediate-temperature solid oxide fuel cells (IT-SOFCs) on porous NiO-BCS-CuO anode substrates using direct electrophoretic deposition (EPD). The effect of increasing the zeta potential when modifying the base suspension of a micro-sized SDC-gn powder (glycine–nitrate method) with the addition of a SDC-lec nanopowder (laser evaporation–condensation) was investigated. Dependences of the current strength on the deposition time and the deposited weight on the EPD voltage were obtained, and evolution of the morphology of the coatings during the modification of the SDC-gn suspension and a suspension of BCS-CuO powder was studied. The compatibility of the shrinkage kinetics of the SDC, the BCS-CuO electrolyte coatings and the NiO-BCS-CuO anode substrate was studied during the high-temperature sintering. Dense BCS-CuO/SDC films of different thicknesses were obtained for the first time on porous NiO-BCS-CuO anode substrates and comprehensive microstructural and electrochemical studies were carried out. The developed technology can be applied to the formation of anode-supported SOFCs with thin-film electrolyte membranes.
