Abstract

We present models we have built for a single H₂S fuelled SOFC. The cell is a planar cell with a circular disc-like electrode assembly and the fuel and air flow through a concentric cylindrical tube assembly. The goal is to model the electrochemical reaction coupled with mass transfer, fluid flow and current/voltage distribution in an yttria stabilized zirconia electrolyte fuel cell assembly operated between 750 and 850°C. The models built range in complexity from an algebraic system of equations that calculates the activation, concentration and ohmic losses, to a 2-dimensional finite element model that solves all the physics in the SOFC simultaneously. The models are validated against experimental data (current density - cell voltage curves) both with and without IR compensation.
