• Numerical simulations using the lattice Boltzmann method (LBM) are developed to elucidate the dynamic behavior of condensed water and gas flow in a polymer electrolyte membrane (PEM) fuel cell. Water management is essential to improve the performance of PEM fuel cells. Since it is difficult to investigate experimentally the liquid water behavior, we applied the lattice Boltzmann method for incompressible two-phase flow with large density difference and evaluate the liquid behavior in gas flow channels in a PEM fuel cell. In this paper, the effects of droplet position, air flow velocity and volume of liquid water droplet on the drain behavior and the efficiency were examined.
