    • Electrode behaviors of Na-Zn liquid metal battery 

      Xu, Junli; Martinez, Ana Maria Cuellar; Osen, Karen Sende; Kjos, Ole Sigmund; Kongstein, Ole Edvard; Haarberg, Geir Martin (Peer reviewed; Journal article, 2017)
      The electroreduction processes on a Mo electrode in a Na-Zn liquid metal battery cell with a molten NaCl-CaCl2-ZnCl2 electrolyte were investigated at 565°C. The effect of the battery operating parameters on the loss rate ...

    • Grounding Strategies for High Voltage Shore Connection of Large Passenger Vessels 

      Mehammer, Eirill Bachmann; Kongstein, Ole Edvard; Brede, Arne Petter (Chapter; Peer reviewed, 2018)
      High voltage shore connection of large passenger vessels is an important way to improve energy efficiency and reduce local and global emissions, as well as noise. However, it is shown that the vessels' steel hulls will act ...

    • 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 ...

    • Soldering a gas diffusion layer to a stainless steel bipolar plate using metallic tin 

      McCay, Katie; Kongstein, Ole Edvard; Ødegård, Anders; Barnett, Alejandro; Seland, Frode (Peer reviewed; Journal article, 2018)
      A novel investigation to decrease the interfacial contact resistance of stainless steel bipolar plates was performed. A thin layer of Sn was electrodeposited onto a bipolar plate and subsequently joined with a gas diffusion ...

    • 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 ...
