The up-to-the-minute progress of the lattice Boltzmann method applied in multiphase flow, mass and heat transfer and electrochemical reactions in the fuel cells was described in detail. As a computational fluid dynamic method, the lattice Boltzmann method is an effective and efficient numerical scheme to analyze the performance of the fuel cell. The numerical simulations performed better understanding of the complex phenomena of fuel cells. These processes were needed for optimum call design. The latest research development was also reviewed in the article. At the same time, the deficiency of the present model was pointed out.
