Abstract

The microporous layers (MPLs) in a polymer electrolyte membrane fuel cell (PEMFC) impact its performance markedly. For the first time, a double-layered microporous layer consisting multi-walled carbon nanotubes (MWCNTs) and carbon black is proposed and fabricated to obtain a better gas diffusion layer (GDL) in PEMFC. The first MWCNTs layer is coated on a carbon paper, followed by coating the second carbon black layer on top of the first MWCNTs layer. The surface morphology was observed under different magnification. The through-plane resistance of the GDL and fuel cell performance were measured. The smoothness of the double-layered MPL appeared to be better than that of the MWCNTs MPL and to be similar to that of the carbon black MPL. The GDL with the double-layered MPL had a lower through-plane resistance than that with either one-layered MPL. The PEMFC with the double-layered MPLs showed a better performance than that with single-layered MPLs under the same carbon material loading.
