Abstract:
In the broad spectrum of chemical energy conversion devices, fuel cells in general and solid oxide fuel cells in particular are attracting substantial interest consiering the significantly higher conversion efficiencies that can be realized through the route using a variety of fuels. Producer gas has been well established as a carbon neutral fuel for internal combustion engines and now the emphasis is on operation of fuel cells. The current work numerically investigates the performance of a solid oxide fuel cell on fuelling with syngas in general with particular emphasis on producer gas fuelled operation. The emphasis is principally on evaluating the influence of gas composition on the fuel cell output in terms of the current density and the utilization factor when clean gas is used. Subsequently, efforts are sought to be directed towards addressing the influence of presence of condensable higher hydrocarbons on the electrodes. The numerical investigation is realized using a three dimensional model of planar type anode supported fuel cell developed using CATIA-V5 as modeling tool and ANSYS ICEM CFD as Meshing tool. The ANSYS FLUENT 14.5 solver is used where the conservation of mass, momentum, and energy equations are inherently handled. The SOFC ADD-ON model is incorporated to solve for electrochemical aspects.
