Modelling of Mass and Heat Transport in Thick-Substrate Thin-Electrolyte Layer SOFCs

摘要

A non isothermal simulation of diffusion and reforming reaction in the anode of a solid oxide fuel cell (SOFC) is presented. The one-dimensional numerical simulation of anode, electrolyte and cathode uses mass and energy balance to determine the concentration and temperature profiles arising perpendicular to the fuel channel. The influence of material properties and operating conditions on the temperature profiles are shown and discussed.
