Numerical Stimulation of Mass Transfer in Cathode Diffusion Layer of PEM Fuel Cell by Lattice Boltzmann Method
Numerical simulation of mass transfer in cathode diffusion layer will be helpful for understanding the mass transfer characteristics and predicting the output characteristics of proton exchange membrane (PEM) fuel cell. In this paper, Lattice Boltzmann method was adopted to simulate mass transfer in cathode diffusion layer of PEM fuel cell, analyze the effect of porous diffusion layer microstructure. The effects of porosity, the pore size and gradual porosity on mass transfer were discussed, and the relationship between liquid saturation and diffusion coefficient was correlated under the existence of liquid water. The results can be used to diffusion layer design and performance analysis of PEM fuel cell.
