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 کاملNumerical Study of Heterogeneous Reactions in an SOFC Anode with Oxygen Addition
Previous experimental studies have shown that addition of small amounts of oxygen to a hydrocarbon fuel stream can control coking in the anode, while relatively large amounts of oxygen are present in the fuel stream in single-chamber solid oxide fuel cells SOFCs . In order to rationally design an anode for such use, it is important to understand the coupled catalytic oxidation/ reforming chemis...
متن کاملSurface Modification of a Doped BaCeO3 to Function as an Electrolyte and as an Anode for SOFCs
Dual functions of BaCe0.8Y0.2O3−a ~BCY! as an electrolyte and as an anode were improved for solid oxide fuel cell ~SOFC! applications. A porous Ce-rich phase with fluorite structure was formed with a depth of ,10 mm from the BCY surface by vaporization of BaO from the BCY surface at 1700°C. The resulting BCY surface showed enough electronic conductivity to provide electrical collection and a hi...
متن کاملThe Numerical analysis of an anode-supported high temperature DIR-PSOFC operating conditions with considering the maximum allowable temperature difference
In the present study, the operating conditions of an anode-supported high temperature direct internal reforming (DIR) planar solid oxide fuel cell (SOFC) are numerically analyzed. SOFCs are the energy conversion devices that produce electricity and heat directly from a gaseous fuel by the electrochemical combination of that fuel with an oxidant. A planar SOFC consists of an interconnect structu...
