A collaborative research team from the Korea Institute of Energy Research (KIER), KAIST, and Pusan National University has successfully developed a groundbreaking catalyst coating technology that significantly boosts the performance of solid oxide fuel cells (SOFCs). The new oxide catalyst coating technique, utilizing nanoscale praseodymium oxide catalysts, triples the efficiency of SOFCs by targeting the oxygen reduction reaction at the air electrode, ultimately increasing the power output of the cells. The research team's electrochemical deposition method, which takes only four minutes and requires no complex equipment, enhances the performance of LSM-YSZ composite electrodes commonly used in industry due to their stability. This method provides a stable and effective coating layer that promotes the oxygen reduction reaction in high-temperature environments. By reducing polarization resistance and increasing peak power density, the catalyst-coated electrodes demonstrate a significant performance improvement over conventional electrodes, showcasing potential applications in various energy conversion devices. Dr. Yoonseok Choi highlighted the economic viability of this technology, as it integrates seamlessly into existing SOFC manufacturing processes, opening doors to industrial utilization. The study, supported by governmental programs, outlines a promising future for this innovative catalyst coating technology in advancing energy conversion and hydrogen production technologies.
