چکیده انگلیسی
A topologically equivalent pore network (TEPN) model is developed for the first time to extract pore networks directly from gas diffusion layer (GDL) microstructures and thus account for all structural features of a GDL material. A generic framework of TEPN modeling is presented to design GDL structures that enable improved water management. With TEPNs used as input to a two-phase flow simulator, constitutive relations and steady-state liquid saturation profiles for carbon paper and carbon cloth are obtained and reported in this work. The results indicate a strong influence of the GDL morphology on water transport characteristics, which helps unravel the structure–performance relationship for GDLs.
