“…Carbon-free, metallic MPL materials have also been explored due to the high electronic conductivity and corrosion resistance of some metals. The work in this field is as yet extremely limited, though research has been conducted into metal powders [134,[176][177][178][179] and steel plates [173]. Leeuwner et al [173] investigated a series of free-standing MPLs fabricated from different materials, one of which was a perforated stainless steel sheet, of the same thickness as SGL 25 BC (50 μm) with a 21% porosity and 500 μm pore size.…”

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.

“…They subsequently immersed the carbon paper in a 5% PTFE solution for hydrophobic treatment and coated it with an MPL to obtain the ultra‐thin GDL that is suitable for PEMFC applications. Fang et al 16 used direct current sputtering to coat titanium on the anode GDL and tested the PEMFC performance. The results revealed that the GDL with titanium coating had a better performance than the one without titanium coating.…”

Summary The object of this study is the manufacturing processes and fluorinated ethylene propylene (FEP) contents on the cell performance of the proton exchange membrane fuel cell (PEMFC). These results are useful for optimizing gas diffusion layer (GDL) fabrication processes and the operating conditions of the PEMFC. A traditional GDL with a micro porous layer (MPL) can enhance the water management ability. For the case of the one‐stage GDL manufacturing process, carbon paper with an FEP content of 10 wt% has the best fuel cell performance and limiting current density. Besides, in the two‐stage GDL fabrication process, when the cathode fuel is air, carbon paper with the same 10 wt% FEP content can delay the occurrence of limiting current density. The types of carbon black have remarkable influences on water management capabilities. It is noted that the XC‐72R carbon powder has a relatively appropriate pore volume to have enough water to keep the membrane moist and avoid water flooding. The higher the gas humidification temperature, the faster the electrochemical reaction rate. But when the operating current density is high, it will generate too much water, resulting in water flooding and a decrease in the PEMFC performance. Therefore, when the cathode fuel is air and the inlet humidification temperature is 80°C for the anode and 50°C for the cathode, the limiting current density can be effectively extended to maintain the cell performance.
