TL;DR: Although the conductivity values of mesoporous acid-free silica xerogels, meso-SiO2-C12EO10OHCF3SO3H or anatase thin films are adequate for fuel cell applications, their performance as an electrolyte in a PEMFC has not been evaluated yet.

TL;DR: It is found that the overall barrier for proton movement within the HPW-meso-silica membranes is determined by the intramolecular proton transfer pathway, which explains why the proton conductivity remains unchanged when the weight percentage of HPW on meso- silica is above 67 wt %.

TL;DR: In this article, the synthesis and characteristics of high-temperature proton exchange membranes based on mesoporous silica nanocomposite functionalized with phosphotungstic acid (HPW) were investigated in detail for applications in PEMFCs and direct methanol fuel cells (DMFCs).

TL;DR: The high membrane proton conductivity, good chemical stability along with high performance at elevated temperatures, and excellent fuel cell performance demonstrate the utility of PA-meso-silica as a new class of inorganic proton exchange membranes for use in the high-temperature proton Exchange membrane fuel cells (PEMFCs).

TL;DR: In this article , a kinetics-controlled interfacial super-assembly strategy is developed, which is capable of preparing asymmetric porous and hollow carbon (APHC) nanoparticles through the precise regulation of polymerization and assembly rates of two kinds of precursors.
