Co-oxidation Modeling for a Syngas Supplied Micro Tubular Solid Oxide Fuel Cell

This paper presents a multi-physique model for a micro tubular solid oxide fuel cell (SOFC) using syngas as fuel. The fuel cell model includes syngas co-oxidation phenomenon and is demonstrated through the electrochemical, fluidic and thermal dynamic characteristics of the fuel cell. The developed model is validated experimentally under varies operating conditions at different reaction temperatures, species partial pressures and entire range of current densities. As an important part of the model, the co-oxidation phenomenon of hydrogen and carbon monoxide is discussed in details. The developed model can be used to design the fuel cell control or diagnostic strategy for industrial applications.
