TL;DR: A novel type of catalysts prepared by high-pressure pyrolysis is reported, featured by hollow spherical morphologies consisting of uniform iron carbide (Fe3 C) nanoparticles encased by graphitic layers, with little surface nitrogen or metallic functionalities.

TL;DR: In this article, the PBI membranes were shown to be irreversibly cured by the thermal treatment and the improved physicochemical characteristics of the membranes after curing were further illustrated by a dramatically improved long-term durability of the corresponding fuel cell MEAs.

TL;DR: In this article, high performance polymers were synthesized of molecular weights from 30 to 94 kDa with good solubility in organic solvents, which showed enhanced chemical stability towards radical attacks under the Fenton test, reduced volume swelling upon acid doping and improved mechanical strength at acid doping levels of as high as about 11 mol H3PO4 per molar repeat polymer unit.

TL;DR: In this article, an acid-base polymer membrane is prepared by doping of imidazolium polysulfone with phosphoric acid for high temperature proton exchange membrane fuel cells.
