The well-known compatibility of the SOFC with hydrocarbon fuels makes the solid oxide fuel cell a strong contender for transportation applications. Gasoline and diesel will continue to be the dominant fuels for decades to come. The 500 million automobiles, the existing fuel distribution system and the economic power of oil and automobile companies combined form a strong inertia in favour of liq...

New oxides of the (NdSr)n+1MO3n+1 (M = Co and Mn or Fe) series are reported. Compounds of composition NdSrCo0.75Fe0.25O4.10, NdSrCo0.75Mn0.25O4.08 and Nd0.5Sr1.5Co0.75Mn0.25O3.86 are the n = 1 members of the Ruddlesden-Popper homologous series (K2NiF4 structural type) as determined by X-ray diffraction and different transmission electron microscopy techniques. Their crystal structure consists o...

The goal of this work is to investigate the feasibility of a hybrid solid oxide fuel cell (SOFC) and gas turbine (GT) system for mobile power production. A system consisting of a gas turbine, a burner, and an SOFC is examined to gain fundamental understanding of the system dynamics. A control oriented dynamic model is developed to provide the critically needed tool for system feasibility analys...

Management of solid oxide fuel cell (SOFC) thermal gradients is vital to limit thermal expansion mismatch and thermal stress. However, owing to harsh operation conditions of SOFCs and limited available space in stack configuration, the number of techniques available to obtain temperature distribution from the cell surface is limited. The authors previously developed and studied a thermocouple a...

A mathematical model is developed to study the performance of a direct carbon solid oxide fuel cell system (DC-SOFC). Simulation results indicate that in anode supported configuration, design parameters (porosity, tortuosity and thickness) play very important role DC-SOFC, presented as polarization curve. The effect Ag content electrode found significant DC-SOFC. operating parameters, namely pr...

most accidents happens because of lack of visibility and not driver’s reaction on time whenan accident occurs. increasing required time for driver’s reaction caused to decreasingaccidents on roadways .intelligent vehicle networks brings enough time for reaction by sendingalert and alternate messages to vehicles on roadway. main propose in this paper is aroundmodulation on reception interval saf...

aminoglycosides are still widely used for treatment of gram-negative sepsis in critically ill patients. the most reported electrolyte abnormalities related to these drugs are hypokalemia, hypomagnesemia, and hypocalcemia. in this study potential benefit of atorvastatin in prevention of amikacin-induced electrolytes imbalances has been evaluated. in this trial 44 patients were assigned to the at...

With an ever-increasing need for thin, flexible and functional materials in electrochemical systems, the layer-by-layer (LbL) technique provides a simple and affordable route in creating new, active electrodes and electrolytes. The LbL technique, which is based upon the alternate adsorption of oppositely charged species from aqueous solution, possesses unprecedented control of materials selecti...
