“…To ensure the uniformity of the coating, it is advisable to conduct the EPD from a suspension with the smallest possible width of size distribution. For this purpose, methods of disaggregation are used, such as ultrasonic treatment (UST) and methods of mechanical dispersing (long ball-milling [46,47], mixing in a magnetic stirrer [48] or processing in a dissolver [49]). In this study, a combination of UST and centrifugation was used, which, despite the short processing time, can significantly increase the proportion of individual particles and obtain narrow particle size distributions in the suspension.…”

This paper presents the results of a comparative study of methods to prevent the loss of barium during the formation of thin-film proton-conducting electrolyte BaCe0.89Gd0.1Cu0.01O3−δ (BCGCuO) on La2NiO4+δ-based (LNO) cathode substrates by electrophoretic deposition (EPD). Three different methods of the BCGCuO film coating were considered: the formation of the BCGCuO electrolyte film without (1) and with a protective BaCeO3 (BCO) film (2) on the LNO electrode substrate and the formation of the BCGCuO electrolyte film on a modified La1.7Ba0.3NiO4+δ (LBNO) cathode substrate (3). After the cyclic EPD in six stages, the resulting BCGCuO film (6 μm) (1) on the LNO substrate was completely dense, but the scanning electron microscope (SEM) analysis revealed the absence of barium in the film caused by its intensive diffusion into the substrate and evaporation during the sintering. The BCO layer prevented the barium loss in the BCGCuO film (2); however, the protective film possessed a porous island structure, which resulted in the deterioration of the film’s conductivity. The use of the modified LBNO cathode also effectively prevented the loss of barium in the BCGCuO film (3). A BCGCuO film whose conductivity behavior most closely resembled that of the compacts was obtained by using this method which has strong potential for practical applications in solid oxide fuel cell (SOFC) technology.

“…To prepare suspensions, the following treatment methods are used: ultrasonic treatment (UST) and mechanical dispersion [40,41], treatment in a dissolver [42], stirring in a magnetic stirrer [43], as well as a combination of UST and centrifugation methods [44]. Suspensions of microsized powders are characterized by better aggregative stability, i.e.…”

Solid oxide fuel cells (SOFCs) have been attracting considerable attention as ecologically friendly and highly efficient power sources with a variety of applications. Modern directions in the SOFCs technology are related to lowering the SOFC operating temperature that require both advanced materials design and development of versatile technologies to fabricate SOFC with thin-film electrolyte membrane to decrease ohmic losses at decreased temperatures. Electrophoretic deposition (EDP) is one of the most technologically flexible and cost-effective methods for the thin film formation currently available. This review highlights challenges and approaches presented in literature to the formation dense thin films based on oxygen-conducting and proton conducting electrolytes, as well as multilayer and composite electrolyte membranes.
