Could the authors address the following concerns about their study? The reliability of the research is potentially undermined by several issues. Key performance metrics, such as the reported high current density (3.89 A/cm² at 850 °C) and 180-hour durability, lack statistical analysis and error margins, which raises questions about reproducibility. While the ultrasonic spraying method is presented as novel, the comparison with conventional techniques is largely qualitative, offering limited evidence to substantiate claims of superiority. Figures illustrating nanostructures and electrochemical data lack raw data transparency, making it difficult to verify their accuracy or rule out potential manipulations. Additionally, the experimental parameters for the ultrasonic spraying process are insufficiently detailed, hindering replicability. Finally, critical claims regarding the role of oxygen vacancies and lattice strain rely on cited literature that requires cross-verification to ensure contextual alignment and appropriate attribution.
