SCREEN PRINTING TECHNOLOGICAL APPROACHES OF MATERIALS FOR SOLID OXIDE FUEL CELLS
Аннотация
This article focuses on the study of materials used in solid oxide fuel cells (SOFCs) and analyzes their properties, advantages, and disadvantages within key components, including electrolytes, anodes, cathodes, and interconnects. Various manufacturing processes and design solutions aimed at enhancing SOFC efficiency and reducing operating temperatures are discussed. The development of new materials and fabrication techniques is crucial to overcoming challenges associated with high-temperature operation, material degradation, and cost reduction, which remain key barriers to widespread commercialization. Particular attention is given to the use of screen printing as a method for forming porous electrode films, which offers high economic efficiency and flexible process parameter control. Screen printing allows for precise deposition of functional layers, ensuring optimal porosity and thickness, which are critical for enhancing electrochemical performance. The study explores the influence of printing parameters on electrode layer properties, an aspect that remains insufficiently researched in the field of SOFCs. A better understanding of these effects can lead to the development of electrodes with improved catalytic activity, mechanical stability, and long-term durability, thereby enhancing the overall performance of SOFCs.
Additionally, the study examines two types of starting electrolyte powders: commercially available gadolinia-doped ceria (GDC) and scandia-stabilized zirconia (ScSZ-n) synthesized via laser evaporation. A particle size analysis using the Brunauer–Emmett–Teller (BET) method revealed significant size discrepancies, necessitating additional processing. The findings contribute to improving the durability and efficiency of SOFCs while facilitating their scalability for industrial applications. By optimizing materials and fabrication techniques, this study provides valuable insights into the advancement of SOFC technology, paving the way for more reliable, cost-effective, and commercially viable fuel cell systems.
