High power density is necessary for applying PEMFC to automotives. This paper describes with the effects of separator geometries on electric generation performance of PEMFC by the use of serpentine and column separators. The result indicates that PEMFC with serpentine separator achieves higher performance than with column separator. This can be explained by the fact that drainage capability of a serpentine type separator is superior to that of column with less contact resistance between a separator and a gas diffusion layer due to the increased contact area.
