    • Conductive epoxy/carbon nanofiber coatings for scale control 

      Edvardsen, Laura; Grandcolas, Mathieu; Lædre, Sigrid; Yang, Juan; Lange, Torstein; Bjørge, Ruben; Gawel, Kamila (Peer reviewed; Journal article, 2021)
      Calcium carbonate (CaCO3) is one of the most widespread scaling minerals and has been a long-standing problem within many industrial sectors. Scaling of calcium carbonate on conductive surfaces can be prevented electrochemically ...

    • Corrosion Investigation by Scanning Electrochemical Microscopy of AISI 446 and Ti-Coated AISI 446 Ferritic Stainless Steel as Potential Material for Bipolar Plate in PEMWE 

      Kellenberger, Andrea; Vaszilcsin, Nicolae; Dan, Mircea Laurentiu; Mitelea, Ion; Geana, Alexandru Adrian; Lædre, Sigrid; Craciunescu, Corneliu M. (Peer reviewed; Journal article, 2024)
      The components of proton exchange membrane water electrolysers frequently experience corrosion issues, especially at high anodic polarization, that restrict the use of more affordable alternatives to titanium. Here, we ...

    • Corrosion Resistance of AISI 442 and AISI 446 Ferritic Stainless Steels as a Support for PEMWE Bipolar Plates 

      Dan, Mircea Laurentiu; Kellenberger, Andrea; Duca, Delia; Vaszilcsin, Nicolae; Craciunescu, Corneliu Marius; Mitelea, Ion; Ercuta, Aurel; Lædre, Sigrid; Khoza, Thulile (Peer reviewed; Journal article, 2023)
      Cost reduction in bipolar plates in proton exchange membrane water electrolyzers has previously been attempted by substituting bulk titanium with austenitic stainless steels protected with highly conductive and corrosion-resistant ...

    • In-Situ Monitoring of Interfacial Contact Resistance in PEM Fuel Cells 

      McCay, Katie; Lædre, Sigrid; Martinsen, Stig-Yngve; Smith, Graham; Barnett, Alejandro Oyarce; Fortin, Patrick (Peer reviewed; Journal article, 2021)
      A new in situ method for measuring the interfacial contact resistance between the bipolar plate and gas diffusion layer of an operating PEM Fuel Cell has been developed. This method involves the insertion of probe wires, ...

    • Issues regarding bipolar plate-gas diffusion layer interfacial contact resistance determination 

      Lædre, Sigrid; Craciunescu, Corneliu M.; Khoza, Thulile; Vaszilcsin, Nicolae; Kellenberger, Andrea; Bolocan, Vlad; Mitelea, Ion; Ercuta, Aurel (Peer reviewed; Journal article, 2022)
      The interfacial contact resistance (ICRBPP-GDL) between the bipolar plates (BPPs) and gas diffusion layers (GDLs) plays a major role in proton exchange membrane-fuel cells (PEMFCs) efficiency. Accordingly, materials selection ...

    • Measuring In Situ Interfacial Contact Resistance in a Proton Exchange Membrane Fuel Cell 

      Lædre, Sigrid; Kongstein, Ole Edvard; Ødegård, Anders; Seland, Frode; Karoliussen, Håvard (Peer reviewed; Journal article, 2019)
      Interfacial contact resistance (ICR) is one of the remaining hurdles for successful implementation of stainless steel bipolar plates in PEM fuel cells. We have developed a reliable method, using thin gold wires, to measure ...

    • Review of asphaltenes in an electric field 

      Farooq, Umer; Lædre, Sigrid; Gawel, Kamila (Peer reviewed; Journal article, 2021)
      Asphaltenes are regarded as troublesome components of crude oils as their precipitation and deposition inside production wells and downstream infrastructure often result in a reduction of production capacity and, in critical ...

    • The role of electrical current mode in calcium carbonate deposition on conductive carbon nanofiber–epoxy coating 

      Edvardsen, Laura; Grandcolas, Mathieu; Lædre, Sigrid; Yang, Juan; Lange, Torstein; Bjørge, Ruben; Gawel, Kamila (Peer reviewed; Journal article, 2024)
      Calcium carbonate is one of the most common scaling minerals. In this paper we have used different electrical current modes (direct current [DC], pulsed DC, and alternating current [AC]) to control the amount, morphology, ...

    • Ta-ITO Coated Titanium Bipolar Plates for Proton Exchange Membrane Water Electrolyzers 

      Lædre, Sigrid; Mendizabal, Lucia; Kongstein, Ole Edvard; Ødegård, Anders; Karoliussen, Håvard; Seland, Frode (Peer reviewed; Journal article, 2022)
      A novel bi-layer coating composed of a tantalum base layer with an Indium Tin Oxide (ITO) top layer was applied to titanium substrates. Samples were polarized ex situ in a parameter study, where the pH, potential and ...
