Abstract
The purpose of this paper is to discuss the loss of voltage in a Solid Oxide Fuel Cell (SOFC) as a result of the irreversible diffusive transport of gases through the microscopic pores of its fuel electrode. The voltage loss is estimated by solving the diffusive-convective equations, and current conduction equations in a computational domain based on data from Focused Ion Beam Scanning Electron Microscopy. The simulation includes both the binary diffusion and the free-molecular diffusion phenomena by employing Cylindrical Pore Interpolation Model. Butler-Volmer model is used to compute the reaction rate. Ion and electron current conduction is based on empirical relationships reported in the literature. The total losses are decomposed to identify the contribution of the mass transport irreversibilities. The parametric study results form a concave surface, showing non-linear relationship between electrode thickness, and diffusion-related voltage losses. The optimal active layer thickness is estimated.
