Recent advances in electrophoretic deposition of thin-film electrolytes for intermediate-temperature solid oxide fuel cells

Abstract

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.

Performance Enhancement of Ce0.8Sm0.2O1.9-Supported SOFC by Electrophoretic Formation of Modifying BaCe0.8Sm0.2O3 and Ce0.8Sm0.1Pr0.1O1.9 Layers

“…The method of electrophoretic deposition (EPD) allows the formation of multilayer electrolyte membranes with precise control of the thickness of the deposited layers. EPD is suitable for the formation of coatings of complex compositions on substrates of arbitrary shape [ 42 , 43 , 44 ]. The peculiarity of the EPD process is the formation of coating in the liquid suspension under the influence of an external electric field.…”

“…Energy consumption is also essential for economic development and prosperity, especially for electricity generation and industrial use ( Babar et al, 2022 ; Hanif et al, 2023a ; Antonova, 2023 ; Gordeev and Porotnikova, 2023 ; Shaheen et al, 2023 ). Fossil fuels are still the primary sources of energy but concerns about greenhouse gas emissions and climate change have increased, forcing the world to explore renewable and sustainable energy sources ( Hanif et al, 2022 ; Irshad et al, 2022 ; Demin and Bronin, 2023 ; Pikalova et al, 2023 ). Fuel cells, particularly solid oxide fuel cells (SOFCs), have become prominent contenders amongst alternative energy sources because of their efficiency, ability to use multiple fuels, and little or no greenhouse gas emissions ( Rafique et al, 2022 ; Hanif et al, 2023b ; Khan et al, 2023 ; Rauf et al, 2023 ; Tarasova et al, 2023 ; Babar et al, 2024 ).…”
