• Multi-Sine EIS for Early Detection of PEMFC Failure Modes 

      Fortin, Patrick; Gerhardt, Michael Robert; Ulleberg, Øystein; Zenith, Federico; Holm, Thomas (Peer reviewed; Journal article, 2022)
      Electrochemical impedance spectroscopy (EIS) is a powerful technique that can be used to detect small changes in electrochemical systems and subsequently identify the source of the change. While promising, analysis is often ...
    • Protons in Oxysulfates, and Sulfides: A First-Principles Study of La2O2S, La2O2SO4, SrZrS3, and BaZrS3 

      Polfus, Jonathan M.; Norby, Truls; Bredesen, Rune (Peer reviewed; Journal article, 2015)
      Sulfur-containing materials may be of importance in devices such as proton conducting fuel cells for energy conversion involving fossil or bioderived fuels. First-principles calculations were employed to elucidate the ...
