| Research Abstract |
This study developed the three dimensional lattice Boltzmann simulation code of the two phase flow in a PEM fuel cell. The objective is to evaluate the gas and liquid behavior in the complicated porous structures and to present optimum cell structures. The developed code clarified the effects of wettability of gas diffusion layer on the drain behavior of condensed water. The simulation also indicated that hydrophilic ribs of separator improves the drainage performance of the gas diffusion layer.
