Biomimetic integrated gas diffusion layer inspired by alveoli for enhanced air-breathing fuel cell performance and stability

“…[52][53][54] Non-uniform temperature distribution can also lead to localized ooding and dehydration, which can accelerate the aging of the proton exchange membrane and even result in the detachment of the proton exchange membrane from the GDL. [55][56][57] These factors have a signicant impact on the durability of the stack. Therefore, in comparison to a single fuel cell, the stack experiences a much higher decay rate.…”

Synergistically Functionalized Pyridinyl- and Phosphine-Oxide-Based Semifluoro-Sulfonated Copolytriazole Membrane Preparation via “Click” Polymerization for Proton Exchange Membrane Applications

“…13−15 Based on the different types of electrolytes, there are several types of HFCs, 1 among which the most important is proton exchange membrane fuel cells (PEMFCs) due to their highly responsive nature, outstanding power production capacity, low working temperature, and simple synthetic procedure with no emission. 16,17 Compared to the other HFCs, PEMFCs demonstrate immense potential in low-emission transportation, industrial and domestic energy distribution, and the portable devices sectors. 2,18−21 The most essential part of PEMFCs is the polymeric membrane, called the proton exchange membrane (PEM).…”

“…8−10 In this context, hydrogen fuel cells (HFCs) flourished as the most promising environmentally sound source of energy production. 11,12 HFCs are known for their excellent energy productivity, perfect size, netzero environmental impact, and low carbon emission. 13−15 Based on the different types of electrolytes, there are several types of HFCs, 1 among which the most important is proton exchange membrane fuel cells (PEMFCs) due to their highly responsive nature, outstanding power production capacity, low working temperature, and simple synthetic procedure with no emission.…”

“…The demand for ecofriendly clean energy and renewal energy sources has been exacerbated tremendously. In the last few decades, with the rapid growth of the world’s population and industrialization, the consumption of fossil fuels, e.g., natural oils, gases, coal, etc., has become massive. , Consequently, the total amount of global primary energy sources has been reduced by more than 79%. , Due to this diminution of fossil fuel resources and their harmful environmental impacts, − the development of alternative sustainable and clean energy production sources has become the most demanding aspect of global policies and economies. − In this context, hydrogen fuel cells (HFCs) flourished as the most promising environmentally sound source of energy production. , HFCs are known for their excellent energy productivity, perfect size, net-zero environmental impact, and low carbon emission. − Based on the different types of electrolytes, there are several types of HFCs, among which the most important is proton exchange membrane fuel cells (PEMFCs) due to their highly responsive nature, outstanding power production capacity, low working temperature, and simple synthetic procedure with no emission. , Compared to the other HFCs, PEMFCs demonstrate immense potential in low-emission transportation, industrial and domestic energy distribution, and the portable devices sectors. ,− …”

Analysis of proton exchange membranes for fuel cells based on statistical theory and data mining

“… 18 , 19 , 20 , 21 , 22 They are considered one of the most promising sustainable power generation technologies globally. 23 , 24 , 25 The PEMFCs consist of multiple layers, 26 , 27 , 28 , 29 with a proton exchange membrane (PEM) in the middle, catalyst layers on both sides, and gas diffusion layers further outward. These five layers form a membrane electrode assembly, with bipolar plates on both sides of the membrane electrode assembly, as shown in Figure 1 .…”
