A Numerical Simulation of a Flow in Pern Fuel Cell Stack Using Lattice Boltzmann Method

摘要：

The objective of the present work using one of the methods of numerical simulation on Computation Fluid Dynamics (CFD), is to identify the diffusion of reactant (hydrogen, oxygen, etc) arising in the proton exchange membrane fuel cell (PEMFC), and the flow characteristics of the product (H2O). The field of this analysis is a two-dimensional channel form and is consisted of Gas channel, Gas Diffusion Layer (GDL), and membrane. This study is analyzed by applying the Lattice Boltzmann BGK D2Q9 model. The actual GDL and membrane have different porosities and thus this research includes solid obstacles with varied forms and sizes according to each area ratio in order to scrutinize this difference.
