Modeling 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 کاملMaterials Engineering for Solid Oxide Fuel Cell Technology
Materials engineering plays vital role in Solid Oxide Fuel Cell (SOFC) technology. For example, engineered porous materials are needed to support delicate electrolyte membranes, where mechanical integrity and effective diffusivity to fuel gases is critical; and to construct fuel cell electrodes, where an optimum combination of ionic conductivity, electronic conductivity, porosity and catalyst d...
متن کاملAn octane-fueled solid oxide fuel cell.
There are substantial barriers to the introduction of hydrogen fuel cells for transportation, including the high cost of fuel-cell systems, the current lack of a hydrogen infrastructure, and the relatively low fuel efficiency when using hydrogen produced from hydrocarbons. Here, we describe a solid oxide fuel cell that combines a catalyst layer with a conventional anode, allowing internal refor...
متن کاملIntegrating Multiple Solid Oxide Fuel Cell Modules
Abstract-According to SECA program guidelines, solid oxide fuel cells (SOFC) will be produced in the form of 3–10 kW modules for residential use. In addition to residential use, these modules can also be used in apartment buildings, hospitals, etc., where a higher power rating would be required. For example, a hospital might require a 250 kW power supply. To provide this power using the SOFC mo...
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...
