Abstract

A gas diffusion layer (GDL) for proton exchange membrane fuel cell has been developed using a new form of partially ordered graphitized nano-carbon black (PUREBLACK® Carbon). This material represents a new class of nano-carbons jointly developed by Superior Graphite Co. and Columbian Chemicals Co. The GDL was characterized by physico-chemical as well as electrochemical methods. The unique process developed for GDL fabrication exhibits excellent fuel cell performance using hydrogen/air at ambient pressure. The microstructure as seen under scanning electron microscope shows excellent surface morphology without any cracks. The membrane electrode assembly (MEA) with PUREBLACK® Carbon based GDLs shows power density as high as 0.55 W/cm2 at 70 °C using hydrogen/air as reactants without any back pressure.
