A three dimensional numerical calculation method has been developed to enable predictions of convective heat transfer for both fuel and oxidant ducts in fuel cells. The unique boundary conditions (thermal and mass transfer) have been recognised and implemented. The effects of mass transfer (mass injection/suction) and entrance effects together with buoyancy driven secondary flow have been investigated for fuel cell ducts. The new results of variable Nusselt numbers taking into account the combined mass transfer and buoyancy effects have been implemented into a SOFC model, previously developed for simulation of planar SOFC with internal reforming, and of integrated SOFC/GT systems. The simulation results show an impact on the evaluation of the fuel cell performance being less than 1%. Further, calculation of the integrated SOFC/GT system performance shows virtually no sensitivity of this improved modelling procedure (less than 0.1 %).
