Rate My Professor Mait Ainsar

In the publication 'DEVELOPMENT of La_0.31Sr_0.58Ti_0.97Ni_0.03O_3-δ THIN FILM SOFC MODEL ELECTRODES' (2023), Ainsar led the study using electrochemical impedance spectroscopy (EIS) at 650 °C on LSTN electrodes with and without Pt current collectors on 10Sc1CeSZ electrolyte. The research demonstrated that embedded Pt serves as the most active component, with the LSTN layer stabilizing Pt-electrolyte contact and preventing grain growth. At the BEChem2024 conference, he presented 'EIS characterization of La_0.31Sr_0.58Ti_0.97Ni_0.03O_3-δ thin film model SOFC electrodes' (2024), analyzing impedance spectra under varying H₂O concentrations and anodic polarization up to +0.4 V. Key findings included size-dependent high-frequency features due to chemical capacitance and electronic conductivity limitations, a minimum polarization resistance at 0.3 V linked to Ni exsolution, and stable chemical capacitance. Ainsar co-authored 'In situ NAP-XPS and electrochemical impedance characterisation of La_0.31Sr_0.58Ti_0.97Ni_0.03O_3-δ thin film model electrodes' (2025, Journal of Power Sources), 'Electrochemical Study of La_0.31Sr_0.58Ti_0.97Ni_0.03O_3-δ Thin Film Model SOFC Electrodes' (2023, ECS Transactions), 'Electrochemical activation of La_0.31Sr_0.58Ti_0.97Ni_0.03O_3-δ SOFC Thin Film Electrodes' (2025), and others, totaling 8 publications listed in ETIS. His contributions advance understanding of SOFC anode performance at lower temperatures for sustainable energy applications.
