Abstract Carbon fiber paper (CFP) is currently the main product of the macroporous substrate (MPS) for the gas diffusion layer (GDL) of proton exchange membrane fuel cells (PEMFCs). The optimization of certain mechanical properties, electrical conductivity, thermal conductivity, air conduction, and mass transfer capabilities together with matched interaction can improve the core competitiveness of CFP. The artical conducts a detailed theoretical analysis of these conducting processes and principles based on CFP's main functions mentioned above. Thinner CFP with a wider pore channel brings about better mass permeability but unsatisfactory mechanical property. Thicker CFP with higher porosity and rougher surface results in worse electrical and thermal conductivity. Meanwhile, the temperature, pressure, time, and other fabrication parameters of CFP are also discussed. With so many contradictories, how to make a balance for real PEMFCs operation and reduce the cost would be a practical strategy for the optimization of CFP in the future.

Using the dry method-prepared polyacrylonitrile based carbon fibers as raw the material, carbon paper applied for proton exchange membrane fuel cells was prepared by the processes of molding, high temperature carbonization, chemical vapor deposition (CVD), and graphitization. The effects of resin carbon content and subsequent heat-treatment process parameters on the properties of carbon paper were studied. The results show that: the resin carbon content is an important factor to affect the density, thickness, through-plane resistivity and porosity of carbon paper. When the resin carbon content is 20%, the thickness of carbon paper is 0.20mm, the density is 0.41g/cm3, and the porosity is 74.5%, in line with requirements of the fuel cell. When the heating time is 4 hours, the porosity is 71.9%.
