Comparison of iron and copper doped manganese cobalt spinel oxides as protective coatings for solid oxide fuel cell interconnects
Talic, Belma; Molin, Sebastian; Wiik, Kjell; Hendriksen, Peter Vang; Lein, Hilde Lea (Journal article; Peer reviewed, 2017)MnCo2O4, MnCo1.7Cu0.3O4 and MnCo1.7Fe0.3O4 are investigated as coatings for corrosion protection of metallic interconnects in solid oxide fuel cell stacks. Electrophoretic deposition is used to deposit the coatings on ... -
Diffusion couple study of the interaction between Cr2O3 and MnCo2O4 doped with Fe and Cu
Talic, Belma; Hendriksen, Peter Vang; Wiik, Kjell; Lein, Hilde Lea (Peer reviewed; Journal article, 2019)Manganese cobalt spinel oxides are promising coating materials for the protection of ferritic stainless steel interconnects in solid oxide fuel cell (SOFC) stacks. The interaction between such coatings and the steel is ... -
Effect of coating density on oxidation resistance and Cr vaporization from solid oxide fuel cell interconnects
Talic, Belma; Falk-Windisch, Hannes; Venkatachalam, Vinothini; Hendriksen, Peter Vang; Wiik, Kjell; Lein, Hilde Lea (Journal article; Peer reviewed, 2017)Manganese cobalt spinel oxides are promising materials for protective coatings for solid oxide fuel cell (SOFC) interconnects. To achieve high density such coatings are often sintered in a two-step procedure, involving ... -
Effect of pre-oxidation on the oxidation resistance of Crofer 22 APU
Talic, Belma; Molin, Sebastian; Hendriksen, Peter Vang; Lein, Hilde Lea (Journal article; Peer reviewed, 2018)The ferritic stainless steel Crofer 22 APU is attractive for the use as interconnects in solid oxide fuel cell stacks. The oxidation rate of this alloy in air at 800 °C was reduced by pre-oxidation at higher temperatures ... -
Oxygen Non-Stoichiometry and Electrical Conductivity of La0.2Sr0.8Fe0.8B0.2O3 − δ, B = Fe, Ti, Ta
Lohne, Ørjan Fossmark; Phung, Tan Nhut; Grande, Tor; Bouwmeester, Henny J. M.; Hendriksen, Peter Vang; Søgaard, Martin; Wiik, Kjell (Journal article; Peer reviewed, 2014)The oxygen non-stoichiometry was determined by coulometric titration for the perovskite oxides La0.2Sr0.8FeO3 − δ and La0.2Sr0.8Fe0.8B0.2O3 − δ (B = Ti4 + and Ta5 +) in the temperature range 600 °C ⩽ T ⩽ 900 °C and the ... -
