Title: Communication—Reactive Sintering of a CoFe₂O₄Coating on Ferritic Stainless Steels for SOFC Interconnect Application

Abstract

A mixed Fe+CoO precursor was successfully utilized to synthesize a dense CoFe₂O₄ spinel coating on the Crofer 22 APU interconnect via reactive sintering at 900°C for 2 h in air without the use of any reduction treatment. Both the uncoated and coated samples were subject to thermal oxidation at 850°C for 500 h in air. Phase constituents, microstructure, and area specific resistance (ASR) of the uncoated and coated samples before and after the oxidation testing were evaluated. The CoFe₂O₄ layer effectively reduced the Cr₂O₃ scale growth and lowered the scale ASR.

Effect of precursor materials on the performance of the NiFe₂O₄-based spinel layer for SOFC cathode-side contact application

Journal Article Yu, Y. T. ; Zhu, J. H. ; Bates, B. L. - Solid State Ionics

Simulated cathode/contact/interconnect cells are used to investigate the effects of different precursors on the microstructure and performance of the thermally-converted NiFe₂O₄-based spinel contact layer. The precursor materials include a mixture of NiO and Fe₂O₃ powders (NiO+Fe₂O₃), a mixture of pure Ni and Fe powders (Ni+Fe), an Fe-Ni alloy (Invar 36) powder, and an Fe-Ni-Co alloy (Kovar) powder. The isothermal area specific resistance (ASR) of the test cells is evaluated at 800°C in air for 1000 h, which shows significant variation depending on the contact precursors. The cells with the metallic precursors exhibit much reduced ASRs compared to the one withmore »« less

Review—(Mn,Co)₃O₄-Based Spinels for SOFC Interconnect Coating Application

Journal Article Zhu, J. H. ; Chesson, D. A. ; Yu, Y. T. - Journal of the Electrochemical Society

With the reduction of solid oxide fuel cell (SOFC) operating temperature to the range of 600 °C–800 °C, Cr-containing ferritic alloys have become the preferred interconnect material, which unfortunately are susceptible to continuous scale growth and Cr volatility at the SOFC operating temperatures. The (Mn,Co)₃O₄ spinel system is widely regarded as the most effective coating for SOFC interconnect protection, due to its high thermal and electrical conductivity, adequate coefficient of thermal expansion, and excellent Cr blocking capability. This article reviews the physical and chemical properties of the (Mn,Co)₃O₄-based spinels; different types of coating precursors and deposition techniques; and the effectsmore »« less

Experimental review of the performances of protective coatings for interconnects in solid oxide fuel cells

Journal Article Reddy, Mareddy Jayanth ; Kamecki, Bartosz ; Talic, Belma ; ... - Journal of Power Sources

Ferritic stainless-steel interconnects are used in solid oxide fuel cells; however, coatings are required to improve their performance. Although several types of coatings have been proposed, they have been scarcely investigated under similar conditions. This study compares the characteristics of uncoated Crofer 22 APU and eight different coatings on Crofer 22 APU for up to 3,000 hours at 800°C. The coatings were deposited at various research laboratories around the world, and the experiments were performed at Chalmers University of Technology, Sweden. Cross-sections of the samples were analysed using scanning electron microscopy and energy-dispersive x-ray spectroscopy. The (Co,Mn)-based coated steels showedmore »« less

Conductive spinels derived from Co–Mn based alloy precursor for SOFC cathode-side contact application

Journal Article Yu, Y. T. ; Zhu, J. H. ; Bates, B. L. - International Journal of Hydrogen Energy

The utilization of gas-atomized Co–Mn based alloy precursor is a promising approach to lowering the sintering temperature of the spinel contact layer and enhancing its performance. In this work, simulated interconnect/contact/cathode cells are employed to investigate the effects of different metallic precursors (i.e., three Co–Mn based alloy powders and a mixture of Co + MnO₂ powders) on the microstructure and performance of the reactively-sintered MnCo₂O₄-based contact layer. While excellent overall electrical performance is observed for all the cells with the four contact precursors during 1000-h testing at 800 °C in air, the cell with the Ce-doped alloy contact precursor showsmore »« less

Tailoring Fe-Base Alloys for Intermediate Temperature SOFC Interconnect Application

Technical Report Zhu, J H ; Brady, M P ; Anderson, H U

This report summarized the research efforts and major conclusions for our SECA Phase I and II project focused on Cr-free or low Cr Fe-Ni based alloy development for intermediate temperature solid oxide fuel cell (SOFC) interconnect application. Electrical conductivity measurement on bulk (Fe,Ni){sub 3}O{sub 4} coupons indicated that this spinel phase possessed a higher electrical conductivity than Cr{sub 1.5}Mn{sub 1.5}O{sub 4} spinel and Cr{sub 2}O{sub 3}, which was consistent with the low area specific resistance (ASR) of the oxide scale formed on these Fe-Ni based alloys. For Cr-free Fe-Ni binary alloys, although the increase in Ni content in the alloysmore »« less
