Summary In this study, we produced reduced graphene oxide (RGO) by reduction of graphene oxide (GO) in Teflon‐lined autoclave, maintained at 100°C for 12 hours, and coated on the anode gas diffusion layer (GDL) of a proton‐exchange membrane fuel cell (PEMFC) to improve the cell performance. Fourier transform infrared spectroscopy and X‐ray photoelectron spectroscopy analysis showed the presence of residual oxygen‐containing functional groups in RGO. Field‐emission scanning electron microscopy images revealed the uniform and adequate coating of the GDLs with RGO. The wettability of RGO‐coated GDL was determined by the sessile drop method and has optimum contact angle 117°. The power densities for the membrane electrode assembly (MEA) with RGO coated on the anode GDL were 30.92%, 41%, and 36.20% higher than those for the MEA without the RGO coating at anode gas humidified temperatures of 25°C, 45°C, and 65°C, respectively.

“…A novel TiVCr hydrogen storage alloy-coated GDL was studied by Fang et al [161]. The fuel cell applying this GDL can be continuously operated for around 10 min at 0.6 V, in the situation close to the hydrogen fuel supply, because a certain amount of hydrogen can be stored in the TiVCr hydrogen storage alloy.…”

Fuel cells are the most clean and efficient power source for vehicles. In particular, proton exchange membrane fuel cells (PEMFCs) are the most promising candidate for automobile applications due to their rapid start-up and low-temperature operation. Through extensive global research efforts in the latest decade, the performance of PEMFCs, including energy efficiency, volumetric and mass power density, and low temperature startup ability, have achieved significant breakthroughs. In 2014, fuel cell powered vehicles were introduced into the market by several prominent vehicle companies. However, the low durability and high cost of PEMFC systems are still the main obstacles for large-scale industrialization of this technology. The key materials and components used in PEMFCs greatly affect their durability and cost. In this review, the technical progress of key materials and components for PEMFCs has been summarized and critically discussed, including topics such as the membrane, catalyst layer, gas diffusion layer, and bipolar plate. The development of high-durability processing technologies is also introduced. Finally, this review is concluded with personal perspectives on the future research directions of this area.

In this paper, an anodic gas diffusion layer (GDL) with a gradient hydrophobic structured microporous layer (MPL) was prepared using a spraying method. The hydrophobicity of the MPL was changed by adding polyvinylpyrrolidone to the MPL close to the catalyst layer side to obtain a bilayer MPL with a gradient hydrophobic structure. By performing the above operation, we designed a double‐layer MPL structure with different hydrophobic gradients. In this study, we analyzed the effect of the gradient hydrophobic structure of bilayer MPL on the electrochemical performance of proton exchange membrane fuel cell by characterizing the physical properties, such as water contact angle, of anode self‐humidified GDL prepared in the laboratory. The study compared the limiting power density of the laboratory‐prepared GDL sample 10% with that of the commercial GDL29BC. The limiting power density of the sample 10% is 1.59, 1.5, and 1.49 W/cm2 under three humidity conditions of 40%, 60%, and 100%, respectively, which improve the performance by 19.5%, 17.2%, and 23.1% over that of the commercial GDL29BC. The anode GDL samples prepared in the laboratory showed good self‐wetting effect, which play a positive role in the improvement of fuel cell performance.
