Paper Abstract

Three layer structure of Solid Oxide Fuel Cell (SOFC), where a thin semi-conducting layer of electrolyte separates the anode from the cathode, shows a strong similarity to typical semiconductor devices built on the basis of P-N junctions, like diodes or transistors. On the basis of this similarity, the attempt of application of Shockley’s formula for the expression of a current-voltage relation of SOFC is presented. The proposed approach enables a more accurate estimation of the ion exchange current, than the approach based on the Tafel’s formula.
