Anode-Supported Solid Oxide Fuel Cells with Thin Film Electrolyte for Operation at Reduced Temperatures
In order to reduce the operating temperature of solid oxide fuel cells (SOFCs), anodesupported cells incorporating thin film (~10 μm) electrolytes in conjunction with anode/electrolyte and cathode/electrolyte interlayers were studied. Anode supported button cells were prepared through a conventional approach and were analyzed via Scanning Electron Microscopy (SEM), Polarization, and Electrochem...
متن کاملAnode-supported thin-film fuel cells operated in a single chamber configuration 2T-I-12
The performance characteristics of anode-supported, thin-film, single chamber fuel cells (SCFCs) have been investigated. Cells, in which Ni+Sm0.15Ce0.85O2 (Samaria doped ceria, SDC) served as the anode and SDC as the electrolyte, were fabricated by dry pressing. High quality, bilayer structures with electrolyte thicknesses as small as 10 Am were prepared with excellent reproducibility. The cath...
متن کاملProperties and synthesis of ultra-thin SOFC structures
This paper presents an initial exploration of the use and possibility of nm thin SOFC electrolyte structures to enhance cell performance. This is addressed, on one hand, by analyzing the extent of interfacial space-charge areas at the electrode-electrolyte interface. A simple thermodynamic treatment shows that such areas have a characteristic dimension in the order of 0.2 nm so that they can be...
متن کاملAn Examination of SOFC Anode Functional Layers Based on Ceria in YSZ
The properties of solid oxide fuel cell (SOFC) anode functional layers prepared by impregnation of ceria and catalytic metals into porous yttria-stabilized zirconia (YSZ) have been examined for operation at 973 K. By varying the thickness of the functional layer, the conductivity of the ceria-YSZ composite was determined to be only 0.015–0.02 S/cm. The initial performance of anodes made with ce...
متن کاملDevelopment of plasma sprayed molybdenum carbide-based anode layers with various metal oxides for SOFC
Air plasma sprayed (APS) coatings provide an ability to deposit a range of novel fuel cell materials at competitive costs. This work develops three separate types of composite anodes (Mo-Mo2C/Al2O3, Mo-Mo2C/ZrO2, Mo-Mo2C/TiO2) using a combination of APS process parameters on Hastelloy ® X for application in intermediate temperature proton conducting solid oxide fuel cells. Commercially availabl...
