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 ... -
Measuring the thermal conductivity of membrane and porous transport layer in proton and anion exchange membrane water electrolyzers for temperature distribution modeling
Bock, Robert; Karoliussen, Håvard; Seland, Frode; Pollet, Bruno; Thomassen, Magnus; Holdcroft, Steven; Burheim, Odne Stokke (Peer reviewed; Journal article, 2019)Water electrolyzers that use a membrane electrolyte between the electrodes are a promising technology towards mass production of renewable hydrogen. High power setups produce a lot of heat which has to be transported through ... -
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 ...
