General Regulation of Air Flow Distribution Characteristics within Planar Solid Oxide Fuel Cell Stacks

For solid oxide fuel cell (SOFC) stacks with a planar design, different structural designs were found to cause very different distribution trends of air flow rates fed to the piled cell units. Many implied optimization guidelines, which were independent of the specific structures, were achieved and verified by extensive 3D multiphysics simulations of the large-scale air flow path models. These conclusions could be very helpful for providing generality in practical structural design and parameter choice for planar SOFC stacks.
