摘要：
Electrical performance of a 3D planar solid oxide fuel cell, with ammonia internal decomposition as fuel and yttrium-stabled zirconia as electrolyte, has been simulated numerically, incorporated with the software Comsol Multiphysics. With the help of the software, gas concentration distribution in an anode/cathode channel as well as current density distribution was demonstrated. The poor gas concentration distribution in the cathode channel is mainly responsible for the poor current density distribution. Furthermore, the effect of current density on the solid oxide fuel cell ohmic and activation overpotential was analyzed. The simulation results conform to the data in the experimental literature well.
