Description
Summary:In this paper we present a study of the of the steady state analysis of a Solid Oxide Fuel Cell Performance. We compare standard gas channels for air feeds to the same model with a porous channel for the air feed. The increased time constant on the air side has the potential to increase the efficiency of the SOFC. The current density, along the electrolyte, the oxygen concentration in the gas channel and the porous cathode, and the potential in the cathode and the electrolyte are compared for the two models. All the simulations are treated at isothermal conditions and applied using COMSOL software.
