    • Double Perovskite Cobaltites Integrated in a Monolithic and Noble Metal-Free Photoelectrochemical Device for Efficient Water Splitting 

      Zhu, Junjie; Guđmundsdóttir, Jónína B.; Strandbakke, Ragnar; Both, Kevin G.; Aarholt, Thomas; Carvalho, Patricia A.; Sørby, Magnus H.; Jensen, Ingvild J.T.; Guzik, Matylda N.; Norby, Truls; Haug, Halvard; Chatzitakis, Athanasios (Peer reviewed; Journal article, 2021)
      Water photoelectrolysis has the potential to produce renewable hydrogen fuel, therefore addressing the intermittent nature of sunlight. Herein, a monolithic, photovoltaic (PV)-assisted water electrolysis device of minimal ...

    • Earth-Abundant Electrocatalysts in Proton Exchange Membrane Electrolyzers 

      Sun, Xinwei; Xu, Kaiqi; Fleischer, Christian; Liu, Xin; Grandcolas, Mathieu; Strandbakke, Ragnar; Bjørheim, Tor Svendsen; Norby, Truls Eivind; Chatzitakis, Athanasios Eleftherios (Journal article; Peer reviewed, 2018)
      In order to adopt water electrolyzers as a main hydrogen production system, it is critical to develop inexpensive and earth-abundant catalysts. Currently, both half-reactions in water splitting depend heavily on noble metal ...

    • 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 ...

    • 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)

    • Mixed proton and electron conducting double perovskite anodes for stable and efficient tubular proton ceramic electrolysers 

      Vøllestad, Einar; Strandbakke, Ragnar; Tarach, Mateusz; Catalán-Martinez, David; Fontaine, Marie-Laure; Beeaff, Dustin; Clark, Daniel Ryan; Serra, José M.; Norby, Truls Eivind (Peer reviewed; Journal article, 2019)
      Hydrogen production from water electrolysis is a key enabling energy storage technology for the large-scale deployment of intermittent renewable energy sources. Proton ceramic electrolysers (PCEs) can produce dry pressurized ...

    • Structural properties of mixed conductor Ba1−xGd1−yLax+yCo2O6−δ 

      Strandbakke, Ragnar; Wragg, David Stephen; Sørby, Magnus Helgerud; Guzik, Matylda; Gunnæs, Anette Eleonora; Szpunar, Iga; Wachowski, Sebastian Lech; Balaguer, Maria; Carvalho, Patricia A.; Mielewczyk-Gryń, Aleksandra; Serra, Jose; Norby, Truls (Peer reviewed; Journal article, 2022)
      Ba1−xGd1−yLax+yCo2O6−δ (BGLC) compositions with large compositional ranges of Ba, Gd, and La have been characterised with respect to phase compositions, structure, and thermal and chemical expansion. The results show a ...
