“…The improvements in the physical properties have shown a significant increase in the cell power densities and improved performance. 33 In 2018, Ozden et al, 34 used graphene in the MPL layer composition to improve GDL properties. The MPL was made by spray deposition of graphene (G-MPL) and morphological, microstructural, physical, electrochemical properties, and the PEMFC performance were investigated.…”

“…Lee et al 32 coated graphene on nickel foam through chemical vapor deposition and showed that the corrosion problem reduced by ninefold, and the contact angle increased by 35% compared with the uncoated foams. By adding carbon nanofibers and graphene to a carbon black‐PTFE composite in a relatively simple and inexpensive process, a series of highly efficient monolayer graphene‐containing, single‐layer GDLs (SL‐GDLs) were successfully prepared by Lee et al 33 The fabricated GDLs showed improved properties such as low electrical resistivity, large average pore sizes, rough surface, and excellent mechanical properties. The improvements in the physical properties have shown a significant increase in the cell power densities and improved performance 33 .…”

Proton exchange membrane fuel cell (PEMFC) offers various advantages such as high power density, high efficiency, low operating temperature, and very short start-up time, which make it a very good candidate to be used in electric vehicles propulsion systems. Among various cell components, the gas diffusion layer (GDL) plays an essential role in the energy conversion of the cell, hence the selection of GDL materials and the fabrication procedure are very important. In the present study, nickel mesh-based double-layer GDL samples containing reduced graphene oxide (rGO) were made and evaluated in terms of various transport properties. The combination of rGO, graphite, and polytetrafluoroethylene (PTFE) in the form of slurry with suitable viscosity, was screen printed on nickel-mesh and baked to form the final GDL structure. Porosity, permeability, contact angle, roughness, thermal, and electrical conductivity of GDL samples were determined to assess the effect of the various components on the quality of the final product. The results of GDL characterization show that the presence of rGO improves all of the GDL transport properties except the electrical conductivity. PTFE, on the other hand, only has a positive effect on improving contact angle and roughness properties. The characterization results also showed that the fabricated GDL samples can perform better than or are comparable with the commercial Toray carbon paper.

The gas diffusion layer (GDL) plays an important role in a proton exchange membrane fuel cell (PEMFC) transporting the current to the collector plates, distributing the reactant gases to the catalyst surface, and evacuating the heat and water that is generated during the redox reactions. Speaking in terms of production cost, the GDL represents between 30% and 50% of the total cost of the membrane electrode assembling (MEA). However, despite its importance in fuel cells, until recent years, the GDLs have not been studied with the same intensity than other MEA components, such as the catalyst or the proton membrane. In this work, we present the production process of a low cost GDL family that was developed at laboratory scale, using a non-woven paper-making process. A relevant aspect of these GDLs is that 40% of their composition is natural cotton, despite which they present good electrical and thermal conductivity, high porosity, good pore morphology, high hydrophobicity and gas permeability. Furthermore, when the GDL with its optimum cotton content was tested in a single open cathode fuel cell, a good performance was obtained, that make of this GDL a promising candidate for its use in fuel cells.
