摘要
VOF model was used to simulate the water removal in the fuel cell gaseous flow channel for the characteristics of the studied device in our laboratory, at high current densities operating conditions. The effect of the air flow speed entering to the channel, the width of the emerging water pore, the hydrophobicity of the diffusion layer and the closeness of the pores in it were evaluated. It was found that water removal is favored by high inlet air speed, wide pore size, a hydrophobic diffusion layer and closer pores.
