Currently, replacing expensive and short-lived materials for supercapacitors based on RuO 2 with more cost-effective high-performance that remain operational after a large number of cycles is challenge. Cerium-based are the most attractive alternative because cerium’s ability to quickly change oxidation state. This work proposes synthesis nanostructured graphene–ceria composite studies its morphological features arising under impact oxygen-free graphene. The mechanism formation nano-ceria...
Polyacrylonitrile and polyheteroarylenes, such as polybenzimidazole (PBI) a polymer of intrinsic microporosity (PIM-1), have been employed to prepare nanoporous electrospun carbon nanofiber (CNF)-based materials for high-temperature proton-exchange (or polymer-electrolyte) membrane (HT-PEM) fuel cells. The CNF mats are obtained by Nanospider (needle-free) electrospinning method from solution followed pyrolysis at 1500 °C form self-supporting with micropores (D < 2 nm) mesopores 2–50 nm)....
To create a new type of catalytic gas diffusion layer for high-temperature hydrogen/air polymer-electrolyte membrane fuel cell (HT-PEMFC), electrospun carbon nanofiber (CNF)-based platinized nanocomposite was formed.
Different polyheteroarylenes, such as m ‐polybenzimidazole, polyphenylene oxide, polymer of intrinsic microporosity (PIM‐1) and poly(N‐phenylene‐benzimidazole) were electrospun to obtain self‐supporting nanofiber mats. The mats after heat treatment, which contains stabilization in air at 250–350 °C pyrolysis 900–1000 under vacuum, convert into carbon paper, a material is suitable for Pt nanoparticle deposition. possibility usage the obtained carbonized nanocomposites entire gas diffusion...
The development of fuel cells is an important part alternative energy studies. High-temperature polymer electrolyte membrane cell (HT-PEMFC) a very promising and commercialized type since it allows the use hydrogen contaminated with CO. However, current advances in HT-PEMFC are based on searching for more sustainable materials electrode assembly. key issue to find new, stable carbonaceous Pt-electrocatalyst supports instead traditional carbon black powder. In present study, we primarily...
Platinum nanoparticle electrocatalysts on carbon nanofibers are engineered and optimized by varying reduction procedure thermal treatment temperature medium.
This article describes procedures and some results of the first study females undergoing 3-day Dry Immersion. The experiment “NAIAD-2020” was carried out at Institute Biomedical Problems (Moscow, Russia) with participation six healthy women volunteers (age 30.17 ± 5.5 years, height 1.66 0.1 m, weight 62.05 8.4 kg, BMI 22.39 2.2 kg/m 2 ) a natural menstrual cycle. During study, standard protocol used, same as for men, minimum period time spent outside immersion bath. Before, during after...
Electrospinning of polyacrylonitrile/DMF dopes containing salts nickel, cobalt, zirconium, cerium, gadolinium, and samarium, makes it possible to obtain precursor nanofiber mats which can be subsequently converted into carbon (CNF) composites by pyrolysis at 1000–1200 °C. Inorganic additives were found uniformly distributed in CNFs. Metal states investigated transmission electron microscopy X-ray photoelectron spectroscopy (XPS). According XPS CNF/Zr/Ni/Gd pyrolyzed 1000 °C, nickel exists as...
The further development of high temperature polymer electrolyte membrane (HT-PEM) fuel cells largely depends on the improvement all components membrane-electrode assembly (MEA), especially membranes and electrodes. To improve characteristics, cardo-polybenzimidazole (PBI-O-PhT)-based complex doped with phosphoric acid is reinforced using an electrospun m-PBI mat. As a result, PBI-O-PhT/es-m-PBInet · nH3PO4 obtained hydrogen crossover values (~0.2 mA cm-2 atm-1), one order magnitude lower...
High-temperature polymer-electrolyte membrane fuel cells (HT-PEM FC) are a very important type of cell since they operate at 150-200 °C, allowing the use hydrogen contaminated with CO. However, need to improve stability and other properties gas diffusion electrodes still hinders their distribution. Anodes based on mat (self-supporting entire non-woven nanofiber material) carbon nanofibers (CNF) were prepared by electrospinning method from polyacrylonitrile solution followed thermal...
The development of phosphorylated polybenzimidazoles (PBI) for high-temperature polymer-electrolyte membrane (HT-PEM) fuel cells is a challenge and can lead to significant increase in the efficiency long-term operability this type.
