Chemical solution deposition of thin films for protonic ceramic fuel cells
Rørvik, Per Martin; Haavik, Camilla; Griesche, David; Schneller, Theodor; Lenrick, Filip; Wallenberg, L. Reine (Peer reviewed; Journal article, 2014)Chemical solution deposition (CSD) offers the opportunity to fabricate very thin electrolyte films at lower temperatures than traditional powder-based methods. CSD methods have not been used much in production of protonic ... -
Development of novel metal-supported proton ceramic electrolyser cell with thin film BZY15–Ni electrode and BZY15 electrolyte
Stange, Marit Synnøve Sæverud; Stefan, Elena; Denonville, Christelle; Larring, Yngve; Rørvik, Per Martin; Haugsrud, Reidar (Peer reviewed; Journal article, 2017)Metal supports for planar MS-PCEC were manufactured using tape-casting of low-cost ferritic stainless steel. A coating protecting the metal support against oxidation was applied by vacuum infiltration and a buffer layer ... -
Electromechanical and biological evaluations of 0.94Bi0.5Na0.5TiO3–0.06BaTiO3 as a lead-free piezoceramic for implantable bioelectronics
Hall, Thomas A.G.; Theodoridis, Konstantinos; Kechagias, Stylianos; Kohli, Nupur; Denonville, Christelle; Rørvik, Per Martin; Cegla, Frederic; van Arkel, Richard J. (Journal article, 2023)Smart implantable electronic medical devices are being developed to deliver healthcare that is more connected, personalised, and precise. Many of these implantables rely on piezoceramics for sensing, communication, energy ... -
Microstructure and performance of La0.58Sr0.4Co0.2Fe0.8O3−d cathodes deposited on BaCe0.2Zr0.7Y0.1O3−d by infiltration and spray pyrolysis
Ricote, Sandrine; Bonanos, Nikolaos; Rørvik, Per Martin; Haavik, Camilla (Peer reviewed; Journal article, 2012)La0.58Sr0.4Co0.2Fe0.8O3−d (LSCF) cathodes have been deposited on proton-conducting BaCe0.2Zr0.7Y0.1O3−d (BCZY27) electrolyte and studied in symmetric cells to investigate the cathode microstructure and electrochemical ... -
Nanocomposites of few-layer graphene oxide and alumina by density functional theory calculations
Polfus, Jonathan M.; Løvvik, Ole Martin; Rørvik, Per Martin; Bredesen, Rune (Peer reviewed; Journal article, 2016)The atomistic and electronic structure and oxygen stoichiometry of nanocomposites between alumina and graphene oxide were investigated by density functional theory calculations. The nanocomposite was described as interfaces ... -
Palladium (Pd) membranes as key enabling technology for precombustion CO2 capture and hydrogen production
Peters, Thijs; Rørvik, Per Martin; Sunde, Tor Olav Løveng; Stange, Marit Synnøve Sæverud; Roness, Frode; Reinertsen, Torkild; Ræder, Henrik; Larring, Yngve; Bredesen, Rune (Peer reviewed; Journal article, 2017)Palladium (Pd) membranes are a promising enabling technology for power generation and hydrogen production with CO2 capture. SINTEF has developed and patented a flexible technology to produce Pd-alloy membranes that ... -
Surface protonic conductivity in chemisorbed water in porous nanoscopic CeO2
Sun, Xinwei; Vøllestad, Einar; Rørvik, Per Martin; Prodinger, Sebastian; Kalantzopoulos, Giorgios N.; Chatzitakis, Athanasios; Norby, Truls (Peer reviewed; Journal article, 2023)CeO2 surfaces play decisive roles in heterogeneous catalysis of important processes. Here, we investigate adsorption and dissociation of water and migration of protons on internal surfaces of nanoscopic porous CeO2. Sorption ...
