摘要
In the present study, the overall cell performance and local transport characteristics of anode-supported solid oxide fuel cells (SOFCs) are numerically investigated by using a two-dimensional mathematical model. The conservation equations of mass, momentum, species, energy and charge are solved to describe the transport processes in fuel cells. The model validation has been performed by comparing the numerical results with experimental data found in the open literature. Effects of cell length and flow direction arrangement on temperature and species distributions are systematically investigated. It is concluded that the performance of SOFCs is significantly increased when the cell length is increased. In addition, the temperature and species distributions are also greatly affected by the cell length and flow direction arrangement.
