We study how water production influences the performance of the fuel cell numerically. We have done two-dimensional simulations by using the Lattice Gas Automaton (LGA) method in order to analyze the gas flow and water distributions in the different type of flow passages. Three kinds of flow passage, that is, serpentine-type, straight-type and column-type were selected and their performances were compared. It is found that the serpentine-type flow is effective for the drainage and the electric generation performance.
