Abstract	:	Fuel cells have the potential of becoming the prime power sources in near future. They offermany advantages over conventional power generators. Fuel cells are being extensivelyresearched where Numerical Modeling plays an increasingly important role. The present studycomprises of a new modular approach to the three dimensional modeling of a Solid Oxide FuelCell (SOFC). The new approach resolves important scales and details of pertinent processesinside various SOFC components. The model calculates the spatial distributions of current,temperature and specie concentrations inside the SOFC. Simulations are performed on cathodeof a SOFC showed interesting results. Also a novel method is devised to model the potentialjump observed at Electrode/Electrolyte interface of a fuel cell. In this method, potential jump isspecified as the source term in the continuity equation for current rather than as a boundarycondition. The source term is derived from an induced potential field by a dipole distribution atelectrode/electrolyte interface. The preliminary results presented show some unique featureswhich could not be detected via experimental studies..
