  This study presents a novel application of Non-Linear Electrochemical Impedance Spectroscopy (NLEIS) in galvanostatic mode for the rapid, non-destructive assessment of metal degradation. By using galvanostatic mode instead of traditional potentiostatic methods, polarization-related challenges are mitigated, enabling more accurate and reliable analysis. The technique allows for the determination of corrosion rates (corrosion current)...

  • D. Parasińska

  - INTERNATIONAL JOURNAL OF HYDROGEN ENERGY - Year 2024

  This article discusses the application of impedance analysis for diagnosing the cathode of a direct methanol fuel cell at various operating temperatures. The Dynamic Electrochemical Impedance Spectroscopy technique coupled with a linear current scan was applied for this purpose. This technique allowed the observation of changes in the cathode's properties in the fuel cell operating under real working conditions. An equivalent model...

  - Wiadomości Chemiczne - Year 2023

  Z biegiem lat reakcje elektrochemiczne przestały być postrzegane jedynie jako eksperymenty laboratoryjne lub proste baterie. Chociaż mechanizm reakcji i budowa prostych reaktorów znana jest ludzkości już od ponad 100 lat w ostatnich latach można zauważyć największy wzrost zainteresowania tą dziedziną. Nowy stale opracowywane są lepsze projekty budowy reaktorów. Modyfikacje to nie tylko rodzaje i formy materiałów, z których wykonane...
