چکیده
Solid oxide fuel cell (SOFC) is a highly efficient power generation system that can be designed in many different geometries including planar and tubular types of cell. Although their operating performance based on the same principles, parameters may unique for each geometry. This study investigates numerically effects configuration by developing finite element method (FEM) SOFC models. The are investigated terms voltage, average current density, power. These illustrated with polarization curves using COMSOL software. As most convenient results this study, although both have own advantages, it concluded increases geometry compared to micro-tubular type under studied conditions.

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 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...
