Single-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 کاملPerformance of an Intermediate-Temperature Fuel Cell Using a Proton-Conducting Sn0.9In0.1P2O7 Electrolyte
Performance of a fuel cell using Sn0.9In0.1P2O7 as the electrolyte was evaluated in the temperature range of 150–300°C under unhumidified conditions. The IR drop and electrode overpotential of the cell were measured separately by the current interruption method. The dc conductivity values of the electrolyte between 150 and 300°C, estimated from the IR drop, were comparable to the ac conductivit...
متن کاملOptimization of temperature and supporting electrolyte for ammonium removal using bioelectrochemical systems
High concentrations of ammonium in drinking water can cause many diseases and environmental problems such as eutrophication. Therefore, high-performance and eco-friendly methods for purification are of great importance and must be considered. Recently, bioelectrochemical systems have been successfully applied for the removal of many pollutants from water and wastewater. In the present work, amm...
متن کاملHigh temperature stability in lanthanum and zirconia-based gate dielectrics
Gate dielectrics composed primarily of lanthana and zirconia were prepared by reactive evaporation. The stability of the layers during high temperature anneals was investigated. By controlling the oxygen partial pressure during heat treatment, lanthana and zirconia films could be protected against reaction with the underlying Si substrate and against the growth of low-« interface layers. The el...
متن کاملLa0.6Sr0.4Co0.2Fe0.8O3 perovskite cathode for Intermediate Temperature Solid Oxide Fuel Cells: A comparative study
In this study the characteristics of two different kinds of La0.6Sr0.4Co0.2Fe0.8O3 (LSCF) powders, one in-house synthesized powder by a co-precipitation method and another one purchased from Fuel Cell Materials Co. (FCM Co., USA), were compared. The co-precipitated powder was prepared by using ammonium carbonate as precipitant with a NH4+/NO3- molar ratio of 2 and calcination at 1000C for 1 h....
