High-performance La0.5Ba0.5Co1/3Mn1/3Fe1/3O3-δ – BaZr1-zYzO3-δ cathode composites via exsolution mechanism for protonic ceramic fuel cells
Rioja-Monllor, Laura; Ricote, Sandrine; Bernuy-Lopez, Carlos; Grande, Tor; O'Hayre, Ryan P.; Einarsrud, Mari-Ann (Journal article; Peer reviewed, 2018)A novel exsolution process was used to fabricate complex all-oxide nanocomposite cathodes for protonic ceramic fuel cells (PCFCs). The nanocomposite cathodes with La0.5Ba0.5Co1/3Mn1/3Fe1/3O3-δ – BaZr1-zYzO3-δ nominal ... -
In situ exsolution synthesis of composite cathodes for protonic ceramic fuel cells
Rioja-Monllor, Laura (Doctoral theses at NTNU;2018:127, Doctoral thesis, 2018)Protonic ceramic fuel cells (PCFCs) have the potential to operate with hydrogen as a fuel in an environmentally friendly manner with no emissions and high electrical efficiency. The lower operation temperature of PCFCs due ... -
Microstructural and compositional optimization of La0.5Ba0.5CoO3−δ—BaZr1−zYzO3−δ (z=0, 0.05 and 0.1) nanocomposite cathodes for protonic ceramic fuel cells
Rioja-Monllor, Laura; Bernuy-Lopez, Carlos; Fontaine, Marie-Laure; Grande, Tor; Einarsrud, Mari-Ann (Journal article; Peer reviewed, 2019)Cathodes are one of the key components of protonic ceramic fuel cells (PCFCs) requiring further development to enhance the performance of PCFCs. This encompasses the optimization of material compositions and microstructures, ... -
Processing of high performing composite cathodes for protonic ceramic fuel cells by exsolution
