NUMERICAL SIMULATION OF HEAT AND MASS TRANSFER WITHIN SOFC: A DEVICE PROMISING FOR FUTURE’S DISTRIBUTED ENERGY SYSTEM

Fuel cell is promising for futures distributed energy system. In order to get accurate solutions for fuel cells performance, a comprehensive numerical model for tubular solid oxide fuel cell (SOFC) with internal reforming and a three dimensional unstructured model for planar SOFC are developed by author. Navier-Stokes equations, energy equation and mass transfer equations for chemical species are solved in conjunction with electrical circuit and electrochemical reactions. Heat produced by ohmic resistance and chemical reactions is considered in these models. Activation and concentration overpotential models are adopted to deal with the activation energy and molar concentration gradients within the porous electrodes. Some progress is reported here in detail. Such information can be used in the optimum design and thermal management of SOFC.
