B-site cation inter-diffusion in yttrium substituted barium zirconate
Hasle, Ida; Waldow, Stephan P.; Gries, Ute N.; De Souza, Roger A.; Vøllestad, Einar; Haugsrud, Reidar (Peer reviewed; Journal article, 2021)B-site cation inter-diffusion in the ABO3 perovskite yttrium-substituted barium zirconate (BZY) was studied at temperatures from 1100 to 1460 °C under reducing and oxidising conditions. The experiments followed two different ... -
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 ... -
Increasing the thermal expansion of proton conducting Y-doped BaZrO3 by Sr and Ce substitution
Dayaghi, Amir Masoud; Haugsrud, Reidar; Stange, Marit Synnøve Sæverud; Larring, Yngve; Strandbakke, Ragnar; Norby, Truls Eivind (Peer reviewed; Journal article, 2021)Proton conducting oxide electrolytes find potential application in proton ceramic fuel cells and electrolyzers operating at intermediate temperatures, e.g. 400–600 °C. However, state-of-the-art proton conducting ceramics ... -

Layered microstructures based on BaZr0.85Y0.15O3−δ by pulsed laser deposition for metal-supported proton ceramic electrolyser cells
Stefan, Elena; Stange, Marit Synnøve Sæverud; Denonville, Christelle; Larring, Yngve; Hildenbrand, Nicolas; Norby, Truls Eivind; Haugsrud, Reidar (Peer reviewed; Journal article, 2017)Planar metal-supported cell designs provide cost-effective scaling-up of solid oxide fuel cells and electrolysers. Here, we report on the fabrication of a BaZr0.85Y0.15O3−δ–NiO (BZY15–NiO) composite electrode and ... -
Oxygen permeability and surface kinetics of composite oxygen transport membranes based on stabilized δ-Bi2O3
Emhjellen, Linn Katinka Susanne Shi; Xing, Wen; Li, Zuoan; Haugsrud, Reidar (Peer reviewed; Journal article, 2022)Composite ceramic membranes based on the ionic conducting Tm-stabilized δ-Bi2O3 (BTM) and the electronic conducting (La0.8Sr0.2)0.99MnO3-δ (LSM) exhibit among the highest oxygen flux values reported for Bi2O3-based membranes. ... -
Surface kinetics and bulk transport in La2Ni0.5Cu0.5O4+δ membranes from conductivity relaxation
Li, Zuoan; Haugsrud, Reidar (Peer reviewed; Journal article, 2023)This work reports conductivity relaxation measurements on both uncoated (1.2 mm thick) and coated (2.0 mm thick) La2Ni0.5Cu0.5O4+δ membranes in the temperature range between 550-850 °C and oxygen partial pressures from ...
