Abstract

PEMFC electrodes with various gas diffusion layers (GDL) were characterized to find out the effect ofGDL on fuel cell performance. The physical properties of GDL such as electric conductivity, porosity, air perme-ability, water flux, PTFE content, etc had close relationship each other and affected on the variation of the cell per-r (MPL) on carbon paper or cloth changed the physicalproperties of GDL and changed the cel performance. The variation of cell performance as a function of the physicalproperties of GDL showed different behaviors according to the amount of current density.
