MODELLING OF THE OHMIC RESISTANCE OF TUBULAR SOLID OXIDE FUEL CELLS

摘要

Different designs have been proposed for tubular solid oxide fuel cells. Due to the non-uniformity of the paths of the electrical charges, the ohmic resistance cannot be evaluated on the basis of the conductivity of the materials involved by means of a simple approach. A theoretical model is presented for the simulation of the ohmic resistance of tubular solid oxide fuel cells. Results are discussed for different cell designs and a parametric analysis is also presented.
