Abstract

The micro-porous layer of gas diffusion layers (GDLs) was fabricated with the carbon slurry dispersed in water contg. sodium dodecyl sulfate (SDS), by wire rod coating process. The aq. carbon slurry with micelle-encapsulation was highly consistent and stable without losing any homogeneity even after adding polytetrafluoroethylene (PTFE) binder for hundreds of hours. The surface morphol., contact angle and pore size distribution of the GDLs were examd. using SEM, Goniometer and Hg Porosimeter, resp. GDLs fabricated with various SDS concns. were assembled into MEAs and evaluated in a single cell PEMFC under diverse operating relative humidity (RH) conditions using H2/O2 and H2/air as reactants. The peak power d. of the single cell using the GDLs with optimum SDS concn. was 1400 and 500 mW cm-2 with H2/O2 and H2/air at 90% RH, resp. GDLs were also fabricated with iso-Pr alc. (IPA) based carbon slurry for fuel cell performance comparison. The compn. of the carbon slurry, specifically SDS concn. played a crit. role in controlling the pore diam. as well as the corresponding pore vols. of the GDLs. [on SciFinder(R)]
