We report a specially designed alkaline polymer electrolyte (APE) with extraordinary stability in both physical and chemical properties, which enables applications of fuel cells and electrolysis at elevated temperatures.

The present work proposes and demonstrates a methodology to capture the effect of operating conditions on ionic conductivity of membranes immersed in alkaline media. Based on reported experimental results for an anion exchange membrane (A-201 by Tokuyama) and a cation exchange membrane (Nafion 211), two novel expressions are developed for the ionic conductivity by incorporating the effects of s...

in present research work, homogeneous anion exchange membranes based on polysulfone (qapsfs) were prepared via chloromethylation, amination and alkalization. in amination step, trimethylamine and n,n,n',n'-tetramethyl-1,6-hexanediamine were used as amination and crosslinking agents, respectively. the chloromethylated polysulfone was characterized by 1hnmr spectroscopy and chloromethylation degr...

In this paper, raspberry hollow Pd nanospheres (HPNs)-decorated carbon nanotube (CNT) was developed for electro-oxidation of methanol, ethanol, and formic acid in alkaline media. The electrocatalyst was fabricated simply by attaching HPNs onto the surface of CNT which had been functionalized by polymer wrapping. The as-prepared HPN-CNTs (CHPNs) were characterized by transmission electron micros...

Palladium-nickel (PdNi) hollow nanoparticles were synthesized via a modified galvanic replacement method using Ni nanoparticles as sacrificial templates in an aqueous medium. X-ray diffraction and transmission electron microscopy show that the as-synthesized nanoparticles are alloyed nanostructures and have hollow interiors with an average particle size of 30 nm and shell thickness of 5 nm.
