The gas diffusion layer (GDL) plays a role as a pathway for electron transport and water management in polymer electrolyte membrane fuel cells (PEMFC). The GDL has been a porous structure made by pressing carbon fibers. In this work, the pitch-based carbon paper (P-CP) was prepared by re-impregnating of binder pitches and PAN-based milled carbon fibers (MCF) at low temperature carbonization process. The influence of MCF content on physicochemical properties of MCF/P-CP was investigated. Interfacial contact resistance, electrical conductivity, thermal conductivity, and tensile strength of MCF/P-CP were measured. |
