Gas diffusion layer (GDL) is one of the critical components in proton exchange membrane fuel cells (PEMFCs) and plays several important roles, such as structural support, reactants permeation, water removal, electrons, and heat conduction. The assembly pressure on bipolar plate is an important factor that affects the performance of PEMFC stack. Not enough assembly pressure leads to leakage of fuels and high contact resistance. Too much pressure, on the other hand, results in damage to the GDL, which increases the GDL Ohmic resistance and interfacial contact resistance, and in turn influences the reactant transport and water removal. The objective of the present study is to develop a numerical model to predict the onset of GDL failure and obtain the maximum assembly pressure on bipolar plate. Composite micromechanical model is applied to calculate the effective elastic properties of GDL; strength failure criterion is established to judge GDL damage with the stress distribution; finite element method model is developed to show the failure zone and the failure propagation in GDL combining the estimated elastic properties and strength failure criterion. Toray TGP-H-060 carbon paper is introduced as a numerical example and the numerical results show good agreements with experimental results. This numerical prediction model is beneficial to understand the basic mechanism of GDL failure and helpful to guide the assembling of PEMFC stack.

Composite film of carbon nanotube (CNT) and polytetrafluoroethylene (PTFE) was formed from dispersion fluids of CNT and PTFE. The composite film showed high electrical conductivity in the range of 0.1–13 S/cm and hydrophobic nature. This composite film was applied to stainless steel (SS) bipolar plates of the proton exchange membrane fuel cell (PEMFC) as anticorrosion film. This coating decreased the contact resistance between the surface of the bipolar plate and the membrane electrode assembly (MEA) of the PEMFC. The output power of the fuel cell is increased by 1.6 times because the decrease in the contact resistance decreases the series resistance of the PEMFC. Moreover, the coating of this composite film protects the bipolar plate from the surface corrosion.
