Performance characteristics of micro, single-chamber, intermediate temperature solid oxide fuel cell (IT-SOFC) has been successfully evaluated by computational simulation based on macro modelling. The system has composite electrodes that are alternately placed on the ceria-based electrolyte. The polarization curve is obtained through the series of computational processes for structural parameters such as distance between the anode and the cathode and the thickness of the electrolyte. Also, the effect of the inflow direction of fuel-air mixture on the performance of the fuel cell is quantitatively investigated. (c) 2005 Elsevier B.V. All rights reserved.
