Abstract

Gas diffusion layers (GDLs) were fabricated using nonwoven C paper as a macro-porous layer substrate developed by Hollingsworth and Vose Company. A com. viable coating process was developed using wire rod for coating micro-porous layer by a single pass. The thickness as well as C loading in the micro-porous layer was controlled by selecting appropriate wire thickness of the wire rod. Slurry compns. with solid loading ≤10% using nano-chain and nano-fiber type carbons were developed using dispersion agents to provide cohesive and homogenous micro-porous layer without any mud-cracking. The surface morphol., wetting characteristics and pore size distribution of the wire rod coated GDLs were examd. using FESEM, Goniometer and Hg porosimetry, resp. The GDLs were evaluated in single cell PEMFC under various operating conditions (temp. and RH) using H and air as reactants. The wire rod coated micro-porous layer with 10% nano-fibrous C based GDLs showed the highest fuel cell performance at 85° using H2 and air at 50% RH, compared to all other compns. [on SciFinder(R)]
