In the present study, a new gas diffusion layer (GDL) with self water management is proposed. It is composed of double layered structure with a hydrophilic layer and a water transpiration layer. This GDL is intended to install outside the cathode catalyst layer. The GDL keeps water needed to humidify solid electrolyte layer by the hydrophilic layer and expels surplus water out of the GDL quickly by the water transpiration layer. In the present report, using simulated layers made of non-conducting hydrophilic inorganic sheet and quick-drying fabrics, the characteristics of the water management are studied experimentally. As the result, the inorganic sheet shows containing large amounts of water and the quick-drying fabrics shows high performance about transpiration. This result shows the effectiveness of the GDL.
