Micro-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 کاملSolid Oxide Fuel Cells for Transportation
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...
متن کاملMaterials for Solid Oxide Fuel Cells
Solid oxide fuel cells (SOFCs) have the promise to improve energy efficiency and to provide society with a clean energy producing technology. The high temperature of operation (500-1000 C) enables the solid oxide fuel cell to operate with existing fossil fuels and to be efficiently coupled with turbines to give very high efficiency conversion of fuels to electricity. Solid oxide fuel cells are ...
متن کاملModeling the Performance of a Tubular Solid Oxide Fuel Cell
In this paper, we develop two computational models for the electrical performance of the tubular solid oxide fuel cell designed by Siemens Westinghouse Corporation. The first model makes simplifying assumptions for activation and concentration polarizations and obtains an analytical solution. In the second procedure, we allow the polarizations to vary with the current density and solve the equa...
متن کاملDynamic Response Analysis of the Planar and Tubular Solid Oxide Fuel Cells to the Inlet Air Mass Flow Rate Variation
The purpose of present study is to investigate the dynamic response of two conventional types of solid oxide fuel cells to the inlet air mass flow rate variation. A dynamic compartmental model based on CFD principles is developed for two typical planar and tubular SOFC designs. The model accounts for transport processes (heat and mass transfer), diffusion processes, electrochemical processes, a...
