Influence of Carbon Based Nanofillers Addition on the Properties of Microporous Layers Prepared via Phase Inversion

Gas Diffusion Layers (GDLs) must have good electrical conductivity and a great hydrophobicity to prevent the pore flooding. These properties can be enhanced by adding a Micro Porous Layer (MPL) based on carbon composites. In this work several MPLs were prepared using carbon-based fillers, such as exfoliated graphite, carbon black and nanotubes, incorporated at very low loadings (
