Synthesis and characterization of Cu-doped (Mn, Co)3O4 spinel nanopowders for solid oxide fuel cell (SOFC) application

One of the major goal of the automotive industry is to improve vehicular fuel efficiency and performance with much lesser percentages of harmful tailpipe emissions.The fuel cell is the best suggestion to replace the car’s fuel. So improving performance and increasing fuel cell efficiency plays an important role in the automotive industry. The modification of Mn-Co spinel oxide (MCO) could be achieved by the addition of a reactive element for conductivity and bonding improvements of coated interconnects applied for solid oxide fuel cell(SOFC). In this study,Cux(Mn, Co)3-xO4 (x=0, 0.2 and 0.4) compounds were synthesized via a pechini-type sol-gel process.The phase and microstructure of synthesized spinel nano powders were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM) equipped with EDS, respectively.The resulting XRD spectra reveal that a pure phase with spinel structure was obtained for modified spinel nanopowders.The resulting XRD spectra reveal that a pure phase with spinel structure was obtained for modified spinel powders. The microstructural characteristics of MCO, Cu0.2 MCO, and Cu0.4MCO synthesized powders were made up of nanoparticles as large 40-92, 200-400, and 400-600 nm in soft agglomerates, respectively.
