Copper Manganese Spinel Coating on a Ferritic Stainless Steel for SOFC Application
Nowadays, Because of daily reduction of fossil fuels and environmental problems caused by using them, Fuel Cells attracted a major attention as clean and efficient way of generating electrical power. Solid Oxide Fuel Cells (SOFCs) have many advantages to other fuel cell types. High working temperature of SOFCs caused serious challenges including high oxidation rate of interconnects, Spallation ...
متن کاملElectrophoretic deposition of MnCr2O4 coating for solid oxide fuel cell metallic interconnects
In the present study, Mn - Cr spinel powder was synthesized through a solid state reaction. In the next step, the electrophoretic deposition (EPD) method was used to apply the MnCr2O4 spinel, as an oxidation-resistant layer, on SUS 430 stainless steel in a potential of 300 V/cm. The coated and uncoated samples were then pre-sintered in air at 900 °C for 3 h followed by cyclic oxidation at 800 °...
متن کاملOxidation Characteristics and Electrical Properties of Doped Mn-Co Spinel Reaction Layer for Solid Oxide Fuel Cell Metal Interconnects
To prevent Cr poisoning of the cathode and to retain high conductivity during solid oxide fuel cell (SOFC) operation, Cu or La doped Co-Mn coatings on a metallic interconnect is deposited and followed by oxidation at 750 ◦C. Microstructure and composition of coatings after preparation and oxidation is analyzed by X-ray diffraction (XRD) and scanning electron microscopy (SEM). High energy micro ...
متن کاملDevelopment of Copper-Ferrite Spinel Coating on AISI 430 Steel Used as Solid Oxide Fuel Cell
The bare and pre-oxidized AISI 430 pieces were screen printed by copper ferrite spinel coatings. Good bonding between the coating and the substrate was achieved by the reactive sintering process of the reduced coating. The energy dispersive X-ray spectroscopy (EDS) analysis revealed that the scale is a double layer consisting of a chromia-rich subscale and an outer Cu/Fe-rich spinel. The result...
