Aliphatic/Aromatic Polyimide Ionomers as a Proton Conductive Membrane for Fuel Cell Applications
TL;DR: Ionomer 1 membrane showed comparable performance to Nafion and was durable for 5000 h without distinct degradation, and microscopic analyses revealed that smaller (<5 nm) and well-dispersed hydrophilic domains contribute to better proton conducting properties.

Anion conductive block poly(arylene ether)s: synthesis, properties, and application in alkaline fuel cells.
Manabu Tanaka,Keita Fukasawa,Eriko Nishino,Susumu Yamaguchi,Koji Yamada,Hirohisa Tanaka,Byungchan Bae,Kenji Miyatake,Masahiro Watanabe +8 more
TL;DR: A well-controlled multiblock structure was responsible for the developed hydrophobic/hydrophilic phase separation and interconnected ion transporting pathway, and the ionomer membranes showed considerably higher hydroxide ion conductivities, than those of existing anion conductive ionomers.

Tuned Polymer Electrolyte Membranes Based on Aromatic Polyethers for Fuel Cell Applications
TL;DR: Isopropylidene tetramethylbiphenylene moieties were more effective than the methyl-substituted fluorenyl groups in giving a high-IEC ionomer membrane with substantial stability to hydrolysis and oxidation.

Design of flexible polyphenylene proton-conducting membrane for next-generation fuel cells.
Junpei Miyake,Ryunosuke Taki,Takashi Mochizuki,Ryo Shimizu,Ryo Akiyama,Makoto Uchida,Kenji Miyatake +6 more
TL;DR: A polyphenylene-based PEM (SPP-QP) that fulfills the required properties for fuel cell applications and extends the limits of existing fluorine-free proton-conductive materials and will help to realize the next generation of PEMFCs via cost reduction as well as the performance improvement compared to the present PFSA-basedPEMFC systems.
