Abstract

A 2D numerical model of a single-chamber fuel cell (SCFC) running on hydrocarbon fuels is presented. The SCFC concept is a novel simplification of a conventional SOFC in which the anode and cathode are both exposed to the same premixed fuel/air mixture, and selective catalysts promote electrochemical oxidation of the fuel at the anode and simultaneous electrochemical oxygen reduction at the cathode. Laboratory tests of small designs of SCFC have demonstrated excellent electrical performances. The model solves for the velocity, temperature, and species distributions, as well as the current density profile, in an SCFC stack for a specified electrical bias. The anode partial oxidation / reforming chemistry use a multi-step elementary reaction mechanism, and electrochemical oxidation of the resulting hydrogen and/or carbon monoxide is included. The set of transport equations in the gas channel is integrated with SIMPLEC algorithm. Simulated trends are in good agreement with experiment.
