DOI: 10.1016/j.ijhydene.2017.03.187
Abstract: Abstract Using the step-growth polycondensation reaction, poly(arylene ether ketone) (PAEK) and activated poly(arylene ether ketone)-NHS intermediates (PAEK-N) were synthesized. PAEK-NHS intermediates with pyridinium groups (PAEK-PYR) were obtained by adding different amounts of PYR groups. The… read more here.

DOI: 10.1016/j.memsci.2020.118133
Abstract: Abstract Benzyltrimethylammonium (BTMA) is most frequently-used organic cations in anion exchange membrane (AEM) materials. However, BTMA-based AEMs always suffer from low ionic conductivity and insufficient alkaline stability for practical alkaline fuel cells. Here, we present… read more here.

DOI: 10.1021/jacs.7b02434
Abstract: H2 oxidation kinetics on Pt in alkaline media are very sluggish, being over 100 times slower than in acidic media, and thus, new and more active H2 oxidation electrocatalysts must be developed in order to… read more here.
