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 کاملSingle-Chamber SOFCs with a Ce0.9Gd0.1O1.95 Electrolyte Film for Low-Temperature Operation
Single-chamber solid oxide fuel cells ~SOFCs! with an anode-supported Ce0.9Gd0.1O1.95 electrolyte were operated in a mixture of butane and air at furnace temperatures of 200-300°C. The electromotive force ~emf! of the cell and the voltage drop were strongly influenced by the catalytic activity of the anode for the partial oxidation of butane. The promotion of hydrogen formation by the addition ...

متن کاملMicro-tubular solid oxide fuel cell based on a porous yttria-stabilized zirconia support
Solid oxide fuel cells (SOFCs) are promising electrochemical energy conversion devices owing to their high power generation efficiency and environmentally benign operation. Micro-tubular SOFCs, which have diameters ranging from a few millimeters to the sub-millimeter scale, offer several advantages over competing SOFCs such as high volumetric power density, good endurance against thermal cyclin...
متن کاملElectrolyte Degradation in Anode Supported Microtubular YSZ-based Solid Oxide Steam Electrolysis Cells at high voltages of operation
Degradation of solid oxide electrolysis cells (SOECs) is probably the biggest concern in the field of high temperature steam electrolysis (HTSE). Anode supported, YSZ-based microtubular solid oxide fuel cells (SOFC) have been tested in fuel cell mode and also at high voltages (up to 2.8V) under electrolysis mode. At high steam conversion rates the cell voltage tends to saturate. Our hypothesis ...
