Three-Dimensional Modelling of a Microtubular SOFC: A Multiphysics Approach
MetadataShow full item record
AbstractMicrotubular Solid Oxide Fuel Cells (µ-SOFC) are suited to a broad spectrum of applications with power demands ranging from a few watts to several hundred watts. µ-SOFC’s possess inherently favourable characteristics over alternate configurations such as high thermo-mechanical stability, high volumetric power density and rapid start-up times. Computational modelling at the design level minimises cost and maximises productivity, giving critical insight into complex SOFC phenomena and their interrelationships. To date, models have been limited by oversimplified geometries, often failing to account for oxidant supply complexities, gas distribution within pores and radiative heating effects (1-3). Here, a three-dimensional Computational Fluid Dynamics (CFD) model of electrodes, electrolyte, current collectors and furnace is considered using COMSOL Multiphysics. The distribution of temperature, current density, electrical potential, pressure and gas concentrations throughout the cell are simulated. Results show good correlation with experimental data and the model is reliable for prediction of fuel cell performance within set parameters.
